AB  - Plants of the genus Prangos are intensively investigated as potential new sources of bioactive isolated products. In this work, the chemical composition of volatile constituents (essential oils and headspace volatiles) and dichloromethane extracts, as well as antimicrobial and antibiofilm activities of essential oils and MFDEs (methanol fractions of dichloromethane extracts) of Prangos trifida from Serbia, were investigated. Volatiles of roots, leaves, stems and fruits, and fatty acids and phytosterols in dichloromethane extracts of roots and fruits were analyzed by GC-FID-MS, whereas coumarins in MFDEs by LC–MS and some isolated coumarins by 1H-NMR. Minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations/minimum fungicidal concentrations (MBCs/MFCs) of essential oils and MFDEs were determined against 13 microorganisms. Antibiofilm activity was assessed against four microorganisms. Additionally, congo red and ergosterol binding assays were conducted to elucidate selected mechanisms of antibiofilm action in the case of Candida albicans. Total of 52 volatile constituents, 16 fatty acids, eight phytosterols and 10 coumarins were identified. Essential oils demonstrated significant activity, surpassing that of commercial food preservatives, against six tested molds from the Aspergillus, Penicillium and Trichoderma genera, as well as against bacteria Staphylococcus aureus and Bacillus cereus. Most of the oils strongly inhibited the formation of biofilms by S. aureus, Listeria monocytogenes and Escherichia coli. MFDEs exhibited noteworthy effects against B. cereus and the tested Aspergillus species, particularly A. niger, and significantly inhibited C. albicans biofilm formation. This inhibition was linked to a marked reduction in exopolysaccharide production, while antifungal mechanisms associated with ergosterol remained unaffected.

AB  - The aim of this work was to investigate the composition of essential oils isolated from fruits of Peucedanum longifolium, and Rhizomatophora aegopodioides (a species which was previously placed in the genus Peucedanum), as well as to compare the obtained results to those available for other previously investigated related species (including taxa which are also, according to some authors, excluded from the genus Peucedanum). Essential oils were obtained via hydrodistillation in a Clevenger-type apparatus and their composition was analyzed using GC-FID and GC-MS. To compare these data to those of previously investigated taxa, a chemometric approach was applied; the data were analyzed using multivariate statistical methods: non-metric multidimensional scaling (nMDS) and hierarchical cluster analysis. The most abundant in P. longifolium essential oil were monoterpenes (79.7%), mostly α-phellandrene (26.2%), β-phellandrene + limonene (21.0%) and myrcene (9.5%), followed by sesquiterpenes (18.3%), mostly germacrene B (9.5%). On the other hand, dominant in R. aegopodioides essential oil were non-terpenic aliphatic hydrocarbons (46.1%), mainly n-undecane (16.5%) and n-nonane (11.3%). In addition, this essential oil also contained a notable quantity of sesquiterpenes (25.1%), with (E)-sesquilavandulol being the most abundant (10.0%). The results of multivariate statistics revealed a clear separation of the essential oil composition of R. aegopodioides and P. longifolium, as well as of P. longifolium and P. officinale. The clustering of the samples of most of the taxa that do not belong to the Peucedanum in the narrow sense (sensu stricto) was also observed, which is in accordance with their recent inclusion in separate genera.

AB  - The composition and anticholinesterase activity of the dried MeOH extracts of Hieracium scheppigianum and H. naegelianum underground parts (rhizomes and roots), as well as the anticholinesterase activity of the dried, previously chemically characterised MeOH extracts of the flowering aerial parts of these two and 26 other Hieracium species in the strict sense (s. str.), were investigated. Furthermore, the anticholinesterase activity of 12 selected secondary metabolites of these extracts was evaluated. Using semi-preparative LC-MS, five caffeoylquinic acids and the sesquiterpene lactone crepiside E were isolated from H. scheppigianum underground parts extract. All these compounds were also identified in the underground parts extract of H. naegelianum. Quantitative LC-MS analysis showed that the analysed underground parts extracts were rich in both caffeoylquinic acids (139.77 and 156.62 mg/g of extract, respectively) and crepiside E (126.88 and 116.58 mg/g). In the Ellman method, the tested extracts showed an interesting anti-AChE and/or anti-BChE activity (IC50=0.56–1.58 mg/mL), which can be explained, at least partially, by the presence of some of their constituents. Among the metabolites tested, the best activity was revealed for the flavonoids apigenin, luteolin and diosmetin, and the sesquiterpene lactone 8-epiixerisamine A (IC50=68.09–299.37 μM).

AB  - Composition of essential oils from ripe dried fruits of Peucedanum longifolium Waldst. & Kit. (PL) and P. aegopodioides (Boiss.) Vandas (PA) was investigated for the first time. Both taxa are distributed on the Balkan Peninsula, Asia Minor and Transcaucasia, and some authors include the last species in a separate genus, Rhizomatophora Pimenov [1]. Plant material was collected in Serbia, PL on Vis hill in Sićevo Gorge, PA in vicinity of Pirot, near village Basara. Oils were obtained by hydrodistillation in Clevenger-type apparatus; yields 0.91% (PL) and 0.02% (PA), w/w. GC-FID-MS analysis revealed presence of 46 components in PL oil and 48 in PA oil, accounting for 98.0% and 90.0% of total oils. PL oil was dominated by monoterpene hydrocarbons (74.4%), mainly α-phellandrene (26.2%), β-phellandrene + limonene (21.0%) and myrcene (9.5%), followed by sesquiterpene hydrocarbons (17.9%), mainly germacrene B (9.5%). On the other hand, most abundant in PA oil were non-terpenic aliphatic hydrocarbons (46.1%), mainly n-undecane (16.5%) and n-nonane (11.3%). However, this oil also contained significant amounts of both non-oxygenated and oxygenated sesquiterpenes (11.4% and 13.6%), with (E)-sesquilavandulol being most prominent (10.0%). Previously, composition of essential oils from some other plant parts of PL was investigated. For example, essential oil from fresh leaves and young stems of this plant was dominated by sesquiterpene β-elemene (24.7%) and monoterpene (E)-β-ocimene (11.7%) [2], which were present in small amounts in dried fruit oil investigated in current study (0.5% and 0.6%).

GC-FID-MS analysis revealed presence of 46 components in PL oil and 48 in PA oil, accounting for 98.0% and 90.0% of total oils. PL oil was dominated by monoterpene hydrocarbons (74.4%), mainly α-phellandrene (26.2%), β-phellandrene + limonene (21.0%) and myrcene (9.5%), followed by sesquiterpene hydrocarbons (17.9%), mainly germacrene B (9.5%). On the other hand, most abundant in PA oil were non-terpenic aliphatic hydrocarbons (46.1%), mainly n-undecane (16.5%) and n-nonane (11.3%). However, this oil also contained significant amounts of both non-oxygenated and oxygenated sesquiterpenes (11.4% and 13.6%), with (E)-sesquilavandulol being most prominent (10.0%). Previously, composition of essential oils from some other plant parts of PL was investigated. For example, essential oil from fresh leaves and young stems of this plant was dominated by sesquiterpene β-elemene (24.7%) and monoterpene (E)-β-ocimene (11.7%) [2], which were present in small amounts in dried fruit oil investigated in current study (0.5% and 0.6%).",

AB  - Composition of dichloromethane and methanol extracts from roots and fruits of Prangos trifida (Mill.) Herrnst. & Heyn s.l. (collected in Sićevo Gorge, Serbia in 2020) was investigated. Extracts were obtained by bimaceration, firstly with dichloromethane, then with methanol; solvents were removed under reduced pressure. GC-FID-MS analysis, conducted after saponification and methylation of samples, showed that palmitic, oleic and linoleic (14.2-51.8%) were dominant fatty acids in root dichloromethane extract, and oleic, linoleic and petroselinic in oily supernatant of fruit dichloromethane extract (10.2-49.9%); in both samples 16 fatty acids were identified. Dominant phytosterols, investigated by GC-FID-MS after unsaponifiable fractions silanization, were β-sitosterol (48.2 and 25.1%) and stigmasterol (14.9 and 12.8%). LC-DAD-MS analysis of dichloromethane and methanol extracts revealed presence of 7-11 furanocoumarins, including oxypeucedanin and imperatorin (up to 105.9 and 49.2 mg/g in fruit dichloromethane extract crystalline precipitate), followed by smaller amounts of oxypeucedanin hydrate, isoimperatorin, heraclenol, heraclenin and/or xanthotoxin. All extracts were rich in one 2',3'-dihydrofuranocoumarin derivative. Previously, such derivative, prantschimgin, as well as imperatorin and isoimperatorin were isolated from this plant and their in vitro anti-inflammatory activity was demonstrated [1]. In current investigation, in root methanol extract, chlorogenic (31.6 mg/g), two dicaffeoylquinic (12.8 and 48.1 mg/g), and smaller amounts of one caffeoylquinic and one feruloylquinic acids were also determined. Furthermore, low quantities of chlorogenic and one dicaffeoylquinic acid and two quercetin-type flavonoids were detected in fruit methanol extract, and one methylluteolin-type flavonoid in both methanol extracts.

AB  - Fast inverted, oil-in-water (o/w) emulsions, also known as SWitch-Oil-Phase (SWOP) emulsions, express the performances of both o/w and water-in-oil (w/o) emulsions during application to the skin, favoring their use as cosmetic carriers in sunscreen products. The objective of this study was to investigate the antioxidant potential (by 2 different methods) and the ultraviolet (UV) absorption ability of SWOP emulsion (S) with incorporated plant-based antioxidants dihydroquercetin (DHQ) and β-carotene (βC), using quercetin (Q) in a reference emulsion, in addition to the evaluation of their physicochemical properties and stability. A new biochemical extra- cellular model for in vitro assessment of antioxidative properties for the SWOP emulsions (S, SQ, SDHQ, and SDHQβC) was developed and compared with the results of 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. The analyses were performed at 20 °C and 37 °C, and oxidative stress parameters were monitored and statistically analyzed. The sun protection factor (SPF) of the samples was determined in vitro. Q and DHQ incorporated into the SWOP emulsion exhibited a strong DPPH radical scavenging ability. Neither incorporated nor pure βC showed DPPH radical scavenging ability at the tested concentrations. Contrary to that, in the bioenvironment conditions, SDHQβC showed minor antioxidative effects increase and also a significant decrease in exogenous pro-oxidative effects, caused by pro-oxidant, when compared to SDHQ. The obtained SPFs of SDHQβC, SDHQ, and SQ were 5.19, 4.65, and 3.35, respectively. The phys- icochemical stability of the emulsions was satisfactory during 1 month storage. The presented results demonstrated that the SWOP emul- sion is a suitable carrier for antioxidants with a photoprotective ability. The novel biochemical approach could be used in addition to DPPH assay with several advantages, relevant for the testing of antioxidant activity of potential active ingredients in cosmetic products.

AB  - The genus Hieracium L. s. str. (Cichorieae, Asteraceae) is one of the most taxonomically complex genera of flowering plants. Chemosystematic significance of triterpenes especially for Asteraceae genera is scarcely assessed. The subject of this research are 28 Hieracium species from Balkan Peninsula (mostly collected at Mt Durmitor, Montenegro): 12 principal belonging to sections Pannosa, Naegeliana, Drepanoidea and Villosa, and 16 hybridogenous originated from the species from those four sections and Glauciformia, Hieracium, Prenanthoidea and/or Italica. Previously, in dried dichloromethane extracts of flowering aerial plant parts, α-amyrin and α-amyrin acetate, as well as β-amyrin, β-amyrin acetate and/or lupeol acetate were identified and quantified using GC-FID-MS. The aim was to evaluate chemosystematic significance of these five triterpenes using multivariate statistical methods (principal components analysis-PCA and non-metric multidimensional scaling-nMDS). Statistical analysis supported the current taxonomical classification of the investigated species, despite overlapping of certain groups. In PCA, all five triterpenes significantly contributed to the differences between the species. Moreover, lupeol acetate could be a significant chemosystematic marker for the most of principal species belonging to the section Pannosa, as well as for some hybridogenous species between H. gymnocephalum Gris. ex Pant. and the members from the other sections.

AB  - The wood-sage (woodland germander) Teucrium scorodonia L. is widespread in European Atlantic coast and in the western part of Central Europe, with some isolated populations in Mediterranean. Recently discovered population on the territory of Serbia, in the valley of Štavica river (vicinity of Loznica), represents the most eastern enclave in the species range. Preliminary chemical analysis of aerial flowering parts and its dried ethanol and hydroethanol (70% v/v) extracts, and assessment of antioxidant potential of selected (hydroethanol) extract were performed. Using appropriate spectrophotometrical methods, total polyphenols in herb (3.48%, expressed as pyrogallol), ethanol and hydroethanol extracts (100.05 and 96.65 mg gallic acid equivalents - GAE/g), tannins in herb (0.96%, expressed as pyrogallol), ethanol and hydroethanol extracts (11.86 and 12.31 mg GAE/g), flavonoids in herb, ethanol and hydroethanol extracts (0.19%, 0.83% and 0.74%, expressed as hyperoside) were quantified. Also, in ethanol and hydroethanol extracts dihydroxycinnamic acid derivatives were determined (8.96% and 8.37%, expressed as acteoside). By LC-MS, in selected (hydroethanol) extract, four flavonoid and five phenylethanoid glycosides were detected; verbascoside (acteoside) was identified and quantified (4.42%) using external standard. This extract exhibited significant total antioxidant activity (1.37 mmol Fe2+/g) and moderate anti-DPPH potential (SC50=51.28 μg/mL).

abstract = "The wood-sage (woodland germander) Teucrium scorodonia L. is widespread in European Atlantic coast and in the western part of Central Europe, with some isolated populations in Mediterranean. Recently discovered population on the territory of Serbia, in the valley of Štavica river (vicinity of Loznica), represents the most eastern enclave in the species range. Preliminary chemical analysis of aerial flowering parts and its dried ethanol and hydroethanol (70% v/v) extracts, and assessment of antioxidant potential of selected (hydroethanol) extract were performed. Using appropriate spectrophotometrical methods, total polyphenols in herb (3.48%, expressed as pyrogallol), ethanol and hydroethanol extracts (100.05 and 96.65 mg gallic acid equivalents - GAE/g), tannins in herb (0.96%, expressed as pyrogallol), ethanol and hydroethanol extracts (11.86 and 12.31 mg GAE/g), flavonoids in herb, ethanol and hydroethanol extracts (0.19%, 0.83% and 0.74%, expressed as hyperoside) were quantified. Also, in ethanol and hydroethanol extracts dihydroxycinnamic acid derivatives were determined (8.96% and 8.37%, expressed as acteoside). By LC-MS, in selected (hydroethanol) extract, four flavonoid and five phenylethanoid glycosides were detected; verbascoside (acteoside) was identified and quantified (4.42%) using external standard. This extract exhibited significant total antioxidant activity (1.37 mmol Fe2+/g) and moderate anti-DPPH potential (SC50=51.28 μg/mL).",

AB  - Antimicrobial and cytotoxic activities were tested for dried MeOH extracts of Hieracium calophyllum (CAL), H. coloriscapum (COL), H. pseudoschenkii (PSE), H. valdepilosum (VAL) and H. glabratum (GLA) herbs (flowering aerial parts), their 2 sesquiterpene lactones (SLs) 8-epiixerisamine A and crepiside E, and dried CH2Cl2 extract of H. scheppigianum (SCH) herb. In microdilution test, extracts showed activity on all tested microorganisms (8 bacteria, 10 fungi). The best effect was exhibited by SCH and CAL on Salmonella Typhimurium (MIC=1.7–2.5 mg/mL MBC=3.4–5.0 mg/mL), and SCH and VAL on Candida albicans (MIC=2.5 mg/mL MFC=5.0 mg/mL). SLs showed notable effect on all tested fungi Aspergillus ochraceus, Penicillium funiculosum, C. albicans and C. krusei (MIC=0.15–0.4 mg/mL MFC=0.3–0.8 mg/mL). In MTT test, extracts inhibited growth of all tested cancer cells (HeLa, LS174 and A549), with the best effect on HeLa (IC50=148.1 μg/mL for SCH, and 152.3–303.2 μg/mL for MeOH extracts); both SLs were active against HeLa cells (IC50=46.2 μg/mL for crepiside E and 103.8 μg/mL for 8-epiixerisamine A). Extracts and SLs showed good safety profile on normal MRC-5 cells.

AB  - This work is focused on nine Heracleum taxa (Apiaceae): H. sphondylium, H. sibiri- cum, H. montanum, H. ternatum, H. pyrenaicum subsp. pollinianum, H. pyrenai- cum subsp. orsinii and H. verticillatum, belonging to the H. sphondylium group, and H. orphanidis, all from sect. Heracleum, as well as H. austriacum subsp. siifolium from sect. Wendia. The aim was to isolate the headspace (HS) fractions from 17 fruit samples (collected from all nine Heracleum taxa) and 13 root samples (col- lected from all eight taxa belonging to sect. Heracleum), to investigate their com- position and chemosystematic significance, as well as to compare these results with those previously obtained for the essential oils isolated by hydrodistillation from the same fruit and root samples. The HS fractions were isolated using an automatic static HS sampler and analysed by GC-FID and GC-MS. The fruit HS fractions were dominated by octyl acetate and/or α-pinene (the taxa from the sect. Heracle- um), or n-octanol (H. austriacum), whereas the root HS fractions mainly contained β-pinene and/or (Z)-β-ocimene (the taxa from the H. sphondylium group), or n-nonane (H. orphanidis). The chemosystematic significance was evaluated using multivariate statistical methods: principal component analysis (PCA), non-metric multidimensional scaling (nMDS) and agglomerative hierarchical clustering based on the unweighted pair-group arithmetic average (UPGMA) algorithm. As in the case of previously investigated essential oils, the statistical analysis of the fruit and root HS fractions generally resulted in the grouping of the investigated H. sphondy- lium group representatives, and within this group, the grouping of morphologically related H. sphondylium and H. montanum and the isolated position of H. verticil- latum. The statistical analysis of the root HS fractions resulted in better separation of the taxa (even compared to previous analysis of the essential oils), i.e. isolated positions of H. ternatum and H. pyrenaicum were observed.

Cilj rada je bila izolacija headspace (HS) frakcija iz 17 uzoraka plodova (prikupljenih od svih devet ispitivanih taksona roda Heracleum) i 13 uzoraka korena (prikupljenih od svih osam ispitivanih taksona iz sect. Heracleum), ispitivanje njihovog sastava i hemosistematskog značaja, kao i poređenje ovih rezultata sa prethodno dobijenim rezultatima za etarska ulja izolovana destilacijom vodenom parom ovih istih uzoraka plodova i korena. Za izolovanje HS frakcija ko- rišćen je automatski statički HS sampler, a za njihovu analizu gasna hromatografija sa FID i MS detekcijom. U HS frakcijama plodova dominirali su oktilacetat i/ili α-pinen (taksoni iz sect. Heracleum), ili n-oktanol (H. austriacum), a u HS frakcijama korena β-pinen i/ili (Z)-β-ocimen (taksoni iz grupe H. sphondylium), ili n-nonan (H. orphanidis). Hemosistematski značaj je procenjen primenom metoda multivarijantne statističke analize: analize glavnih komponenti (PCA), nemetričkog multidimenzionalnog skaliranja (nMDS) i aglomerativne hijerarhijske klaster analize zasnovane na unweighted pair-group arithmetic averages (UPGMA) algoritmu. Kao i u slučaju prethodno ispitivanih etarskih ulja, u statističkoj analizi HS frakcija plodova i korena generalno je primećeno grupisanje ispi- tivanih predstavnika grupe H. sphondylium, kao i grupisanje morfološki srodnih H. sphondylium i H. montanum i izolovan položaj H. verticillatum u okviru ove grupe. Statistička analiza HS frakcija korena rezultovala je boljim razdvajanjem taksona (čak i u poređenju sa prethodnom analizom etarskih ulja), tj. primećene su izolovane pozicije H. ternatum i H. pyrenaicum.

AB  - Dry MeOH extract of Ferula heuffelii (Apiaceae) underground parts was tested for spasmolytic, gastroprotective and antioxidant activities. HPLC analysis revealed that chlorogenic acid (CGA; 34.6 mg/g) was its main constituent. Extract in vitro exhibited notable total antioxidant activity (FRAP value=1.0 μmol Fe2+/mg), and scavenging of DPPH (SC50=62.5 μg/ml) and •OH radicals (49.5 % at 20 μg/ml in 2-deoxyribose assay). In vitro on isolated rat ileum, extract exhibited significant spasmolytic activity, i. e., it showed 124.6 % of maximal atropine effect on spontaneous contractions (at 100 μg/ml), and reduced spasmogenic effect of KCl (80 mm) to 44.4 % (at 60 μg/ml) and of highest applied concentration of ACh to 26.3 % (at 120 μg/ml). In parallel experiments, spasmolytic effect of CGA was also demonstrated. In acute EtOH-induced gastric ulceration model in rats, extract (100 mg/kg p.o.) showed significant gastroprotective effect (gastric damage score 0.50), similar to ranitidine (20 mg/kg p.o.). Obtained results showed that tested F. heuffelii polar extract represents new herbal preparation with potential use against some gastrointestinal complaints.

AB  - Significance of pharmacognostic studies on previously untested or scarcely tested
wild plants is constantly rising, considering growing demand of pharmaceutical industry for
new bioactive isolates, including essential oils and extracts. Accordingly, comprehensive
research that included all nine taxa of genus Heracleum L. (Apiaceae) (three of which are
endemic) from Serbia, Montenegro, North Macedonia and Slovenia was performed (60
samples of various plant organs collected from 14 localities in period 2009-2016). Plants of
this genus (cow parsnips) got their Latin name after ancient hero Heracles, because of their
habitus and use in folk medicine in treatment of various diseases. Also, some of them were
the main ingredient of borscht, a traditional dish in Eastern European countries. They are
interesting because of wide range of metabolites: from essential oil components, coumarins,
flavonoids, phenolic acids, triterpenes and phytosterols, to some specific fatty acids. Analysis
of these secondary and primary metabolites was performed using modern chromatographic
and spectroscopic techniques (GC-FID-MS, LC-MS and NMR). In the case of 35 selected
essential oils, antimicrobial, cytotoxic and/or antioxidant activities were also tested. It was
revealed that studied plants represent potential new sources of compounds of importance
not only for pharmaceutical, but also for cosmetic, food and chemical industries. For
components of essential oils and furanocoumarins, by multivariate statistical analysis,
chemosystematic significance was also established. Results of pharmacological
investigations of essential oils indicated their importance as potential new medicinal plant
raw materials, under condition of respecting established maximum daily intakes for those
oils in which furanocoumarins were detected.
AB  - Značaj farmakognozijskih studija na do sada neispitivanim ili nedovoljno ispitivanim
samoniklim biljkama konstantno raste s obzirom na sve veće potrebe farmaceutske
industrije za novim bioaktivnim izolatima, uključujući i etarska ulja i ekstrakte. U skladu sa
tim, sprovedeno je opsežno istraživanje svih devet taksona roda Heracleum L. (Apiaceae) (od
kojih su tri endemična), sa područja Srbije, Crne Gore, Severne Makedonije i Slovenije (60
uzoraka različitih biljnih organa sakupljanih sa 14 lokaliteta u periodu od 2009-2016. god.).
Biljke ovog roda (mečje šape) dobile su latinski naziv po antičkom heroju Heraklu, kako zbog
svog habitusa, tako i zbog primene u narodnoj medicini u lečenju različitih bolesti. Takođe,
neke od njih bile su glavni sastojak boršča, tradicionalnog jela u zemljama istočne Evrope.
Interesantne su zbog širokog spektra metabolita: od komponenti etarskih ulja, kumarina,
flavonoida, fenolkarboksilnih kiselina, triterpena i fitosterola, sve do nekih specifičnih
masnih kiselina. Ispitivanje navedenih sekundarnih i primarnih metabolita ovih taksona
sprovedeno je uz korišćenje savremenih hromatografskih i spektroskopskih tehnika (GC-

abstract = "Significance of pharmacognostic studies on previously untested or scarcely tested
wild plants is constantly rising, considering growing demand of pharmaceutical industry for
new bioactive isolates, including essential oils and extracts. Accordingly, comprehensive
research that included all nine taxa of genus Heracleum L. (Apiaceae) (three of which are
endemic) from Serbia, Montenegro, North Macedonia and Slovenia was performed (60
samples of various plant organs collected from 14 localities in period 2009-2016). Plants of
this genus (cow parsnips) got their Latin name after ancient hero Heracles, because of their
habitus and use in folk medicine in treatment of various diseases. Also, some of them were
the main ingredient of borscht, a traditional dish in Eastern European countries. They are
interesting because of wide range of metabolites: from essential oil components, coumarins,
flavonoids, phenolic acids, triterpenes and phytosterols, to some specific fatty acids. Analysis
of these secondary and primary metabolites was performed using modern chromatographic
and spectroscopic techniques (GC-FID-MS, LC-MS and NMR). In the case of 35 selected
essential oils, antimicrobial, cytotoxic and/or antioxidant activities were also tested. It was
revealed that studied plants represent potential new sources of compounds of importance
not only for pharmaceutical, but also for cosmetic, food and chemical industries. For
components of essential oils and furanocoumarins, by multivariate statistical analysis,
chemosystematic significance was also established. Results of pharmacological
investigations of essential oils indicated their importance as potential new medicinal plant
raw materials, under condition of respecting established maximum daily intakes for those
oils in which furanocoumarins were detected., Značaj farmakognozijskih studija na do sada neispitivanim ili nedovoljno ispitivanim
samoniklim biljkama konstantno raste s obzirom na sve veće potrebe farmaceutske
industrije za novim bioaktivnim izolatima, uključujući i etarska ulja i ekstrakte. U skladu sa
tim, sprovedeno je opsežno istraživanje svih devet taksona roda Heracleum L. (Apiaceae) (od
kojih su tri endemična), sa područja Srbije, Crne Gore, Severne Makedonije i Slovenije (60
uzoraka različitih biljnih organa sakupljanih sa 14 lokaliteta u periodu od 2009-2016. god.).
Biljke ovog roda (mečje šape) dobile su latinski naziv po antičkom heroju Heraklu, kako zbog
svog habitusa, tako i zbog primene u narodnoj medicini u lečenju različitih bolesti. Takođe,
neke od njih bile su glavni sastojak boršča, tradicionalnog jela u zemljama istočne Evrope.
Interesantne su zbog širokog spektra metabolita: od komponenti etarskih ulja, kumarina,
flavonoida, fenolkarboksilnih kiselina, triterpena i fitosterola, sve do nekih specifičnih
masnih kiselina. Ispitivanje navedenih sekundarnih i primarnih metabolita ovih taksona
sprovedeno je uz korišćenje savremenih hromatografskih i spektroskopskih tehnika (GC-
FID-MS, LC-MS i NMR). U slučaju 35 odabranih etarskih ulja ispitivane su i antimikrobna,
citotoksična i/ili antioksidantna aktivnost. Utvrđeno je da su proučavane biljke potencijalno
novi izvori jedinjenja od značaja ne samo za farmaceutsku, već i za kozmetičku,
prehrambenu i hemijsku industriju. Za komponente etarskih ulja i furanokumarine
ustanovljeno je multivarijantnom statističkom analizom da imaju i hemosistematski značaj.

AB  - In this study composition and antimicrobial activity of essential oils of roots, leaves,
stems and fruits of Prangos trifida (Mill.) Herrnst. & Heyn s.l. (Apiaceae) were investigated.
Plant material was collected in Sićevo Gorge (Kusača) in 2020. Essential oils were isolated by
hydrodistillation in Clevenger-type apparatus and analyzed by GC-FID-MS. Antimicrobial
activity was tested by microdilution method against food contaminants: Gram-positive
(Staphylococcus aureus, Bacillus cereus and Listeria monocytogenes), Gram-negative bacteria
(Escherichia coli, Enterobacter cloacae and Salmonella Typhimurium), and molds (Aspergillus
fumigatus, A. niger, A. versicolor, Penicillium funiculosum, P. verrucosum var. cyclopium and
Trichoderma harzianum); artificial food preservatives E211 and E224 were used as controls.
Dominant constituents of essential oils were monoterpenes (66.2-87.2%). Terpinolene
(36.2%) and p-cymene (11.5%) prevailed in root oil, (E)-β-ocimen (23.2%) and terpinolene
(18.1%) in leaf oil, p-cimen-8-ol (21.8%) and p-cimen (14.1%) in stem oil, and p-cimen
(25.4%) and limonene (14.4%) in fruit oil. Essential oils showed significant antifungal
activity (MIC=0.10-0.78 mg/mL; MFC=0.20-1.56 mg/mL), better compared to both tested
commercial preservatives, and interesting antibacterial activity (MIC=0.20-6.25 mg/mL;
MBC=0.39-12.5 mg/mL), which was in the case of root and stem oils better than activity of
both preservatives against S. aureus and B. cereus. It should be noted that composition of
tested oils was in accordance with composition of the oils of this plant from vicinity of
Madrid (1) and from Crimea (2), while their antimicrobial activity was tested in this work for
the first time. Obtained results justify further research of P. trifida essential oils as new
natural food preservatives.

AB  - In this work, composition and antioxidant activity of dry dichloromethane and methanol extracts of Heracleum ternatum Velen. (Apiaceae) leaves and flowers from Mt Durmitor (Montenegro) were investigated. Using LC-MS, five furanocoumarins were identified in leaf dichloromethane extract (accounting for 23.00 mg/g of dry extract) and eight in flower dichloromethane extract (60.47 mg/g). Dominant in leaf extract was heraclenin (11.64 mg/g), followed by imperatorin (5.90 mg/g), and in flower extract heraclenol (17.55 mg/g), followed by heraclenin (15.04 mg/g). LC-MS analysis revealed eight flavonol glycosides in leaf methanol extract (accounting for 16.18 mg/g of dry extract) and 11 in flower methanol extract (65.82 mg/g), as well as chlorogenic acid in both extracts (4.72 mg/g and trace, respectively). Among detected flavonoids, dominant was quercetin 7-O-rhamnosyl 3-O-glucoside (vincetoxicoside A; 7.95 and 16.77 mg/g), followed by biosides and triosides of kaempferol and methylquercetin. Content of total polyphenols, determined spectrophotometrically using Folin-Ciocalteu reagent, was 87.29 and 98.12 mg of gallic acid equivalents/g of dry methanol extracts. Among methanol extracts, polyphenol richer flower extract showed higher, spectrophotometrically determined, total antioxidant and anti-DPPH activities compared to leaf extract (FRAP=0.80 and 0.65 mmol Fe2+/g; DPPH SC50=83.12 and 90.95 μg/mL). Dichloromethane extracts showed lower anti-DPPH activity (SC50=860.58 and 515.76 μg/mL).

AB  - Dry MeOH extracts of the twig barks of Pyrus communis subsp. pyraster, P. spinosa and their hybrid P.×jordanovii nothosubsp. velenovskyi, collected in wild in Serbia, were analyzed. By LC/MS, the contents of arbutin (99.9–131.0 mg/g), chlorogenic acid (2.2–6.3 mg/g), catechin (1.0–5.3 mg/g) and total dimeric and trimeric procyanidins (42.2–61.3 mg/g), including procyanidin B2 (8.9–17.2 mg/g), were determined. Colorimetri- cally, high contents of total phenolics (436.2–533.4 mg GAE/g) and tannins (339.4–425.7 mg GAE/g), as well as strong total antioxidant activities (FRAP values 4.5–5.9 mmol Fe2+ /g), and DPPH (SC50 = 6.6–7.1 μg/ml) and hydroxyl radical (SC50 = 447.1–727.7 μg/ml) scavenging abilities were revealed. In vitro, all extracts exhibited notable inhibition of α-amylase (IC50 = 310.8–617.7 μg/ml) and particularly strong inhibition of α-glucosidase (IC50 = 2.1–3.7 μg/ml). Molecular docking predicted that among identified compounds procyanidin B2 is the best inhibitor of these carbohydrate-digesting enzymes. Obtained results showed that the barks of investigated Pyrus hybrid and its parent taxa have similar composition and bioactivity.

AB  - Present study investigated triterpene profile, antihyperalgesic and antiedematous activities of Hieracium scheppigianum flowering aerial parts dichloromethane extract (SCH), and antihyperalgesic and antiedematous activities of previously chemically characterised polyphenol-rich H. glabratum and H. calophyllum flowering aerial parts methanol extracts (GLA and CAL, respectively). α- and β-Amyrin and their acetates, and lupeol acetate were identified and quantified in SCH by GC-FID and GC-MS. In carrageenan-induced localised inflammation model in rats, SCH and GLA (50–200 mg/kg, p.o.) produced significant and dose-dependent antihyperalgesic effect of 26.9%–56.2% (ED50=163.0 ± 26.5 mg/kg) and 25.3%–51.6% (ED50=211.6 ± 70.6 mg/kg), respectively, and CAL (200 mg/kg, p.o.) exhibited effect of 38.1%. Extracts did not significantly reduce paw edema. SCH and GLA, which demonstrated higher (over 50%) antihyperalgesic efficacy, were tested in a rotarod test (200 mg/kg, p.o.) and no alteration of motor coordination was observed. Also, acute administration of SCH and GLA in mice (2000 mg/kg, p.o.) caused neither mortality nor toxicity.

AB  - Velika mečja šapa, Heracleum sibiricum L. (Apiaceae), autohtona je u severnoj, istočnoj
i centralnoj Evropi, kao i na Balkanskom poluostrvu i u Sibiru (1). Infuz pripremljen od
nadzemnih delova ove biljke se u narodnoj medicini na Balkanskom poluostrvu koristi kao
aperitiv i za tretman dijareje i drugih gastrointestinalnih tegoba (2). Prethodna ispitivanja H.
sibiricum nisu uključivala analizu polifenola, dok su furanokumarini do sada analizirani u
korenu, plodovima i listovima (1, 3).
Cilj ovog rada bio je ispitivanje hemijskog sastava i antioksidantne aktivnosti
metanolnih i dihlormetanskih ekstrakata listova i cvasti ove biljke.
Osušen biljni materijal (sakupljen na Staroj Planini u Srbiji u julu 2014. god.)
ekstrahovan je sukcesivno dihlormetanom i metanolom (u oba slučaja bimaceracijom
72+48 h, sa odnosom droga rastvarač 1:10 m/V). Rastvarači su uklonjeni pod sniženim
pritiskom. Hemijski sastav dobijenih suvih ekstrakata analiziran je LC-MS metodama.
Dodatno, u slučaju metanolnih ekstrakata spektrofotometrijski je utvrđen sadržaj ukupnih
polifenola pomoću Folin‐Ciocalteu reagensa. Antioksidantna aktivnost metanolnih ekstrakata
ispitana je spektrofotometrijskim FRAP i DPPH testovima, a dihlormetanskih ekstrakata
DPPH testom.
LC-MS analiza pokazala je da su suvi metanolni ekstrakti listova i cvasti bili vrlo slični.
U njima su određene značajne količine heterozida kvercetina i kemferola (154,30 i
144,20 mg/g suvog ekstrakta). Najzastupljeniji su bili vincetoksikozid A (kvercetin 7-O-ramnozil
3-O-glukozid; 26,83 i 29,61 mg/g), kemferitrin (kemferol 3,7-di-O-ramnozid; 33,62
i 34,68 mg/g) i jedan kvercetin dezoksiheksozil dezoksiheksozid (69,06 i 79,91 mg/g).
U ekstraktu listova detektovano je još šest, a u ekstraktu cvasti još pet heterozida ovih
flavonola. Takođe, u oba ekstrakta identifikovana je hlorogenska kiselina (19,31 i
4,12 mg/g). Spektrofotometrijski utvrđen sadržaj ukupnih polifenola iznosio je 126,08 i
125,33 mg ekvivalenata galne kiseline/g.
U suvom dihlormetanskom ekstraktu listova LC-MS metodom detektovane su male
količine furanokumarina izopimpinelina i bergaptena (ukupno 0,22 mg/g suvog ekstrakta),
čije je prisustvo i ranije utvrđeno (3). U ekstraktu cvasti, pored dva navedena, identifikovano
je još šest furanokumarina i svi su takođe bili prisutni u malim količinama (ukupno
20,07 mg/g); najzastupljeniji je bio bergapten (4,84 mg/g), a po količini ga je sledio
biakangelikol (3,29 mg/g).
Ukupna antioksidantna aktivnost suvih metanolnih ekstrakata listova i cvasti (FRAP
vrednosti 1,08 i 0,94 mmol Fe2+/g), kao i antiradikalska aktivnost (DPPH SC50 vrednosti
64,10 i 64,77 μg/mL) bile su u korelaciji sa sadržajem ukupnih polifenola. Anti-DPPH
aktivnost suvih dihlormetanskih ekstrakata bila je očekivano niža (SC50 vrednosti 636,19 i
790,20 μg/mL).
Može se zaključiti da listovi i cvasti H. sibiricum predstavljaju nove izvore jedinjenja sa
poznatom antioksidantnom aktivnošću.
AB  - Siberian cow parsnip, Heracleum sibiricum L. (Apiaceae), is autochthonous to
northern, eastern and central Europe, Balkan Peninsula and Siberia (1). Infusion prepared
from aerial parts of this plant is used in folk medicine on Balkan Peninsula as aperitif and to
treat diarrhea and other gastrointestinal complaints (2). Previous studies of H. sibiricum
have not included polyphenol analysis, while furanocoumarins were analyzed in roots, fruits
and leaves (1, 3).
In this work, chemical composition and antioxidant activity of methanol and
dichloromethane extracts obtained from leaves and flowers of this plant were investigated.
Dried plant material, collected on Mts Stara Planina (Serbia) in July 2014, was
extracted successively with dichloromethane and methanol (in both cases by bimaceration
72+48 h; drug/solvent=1:10 w/V). Solvents were removed under reduced pressure. The
composition of obtained dry extracts was analyzed by LC-MS methods. Additionally, for
methanol extracts, total phenolics contents were determined spectrophotometrically using
Folin-Ciocalteu reagent. Antioxidant activity of methanol extracts was tested by
spectrophotometric FRAP and DPPH assays, and of dichloromethane extracts by DPPH assay.
LC-MS analysis showed that investigated leaf and flower dry methanol extracts were
very similar. In both extracts, significant amounts of quercetin and kaempferol glycosides
(154.30 and 144.20 mg/g of dry extract) were determined. Dominant were vincetoxicoside A
(quercetin 7-O-rhamnosyl 3-O-glucoside; 26.83 and 29.61 mg/g), kaempferitrin (kaempferol
3,7-di-O-rhamnoside; 33.62 and 34.68 mg/g) and one quercetin deoxyhexosyl
deoxyhexoside (69.06 and 79.91 mg/g). Six more glycosides of these flavonols were detected
in the leaf extract and five more in the flower extract. Also, chlorogenic acid (19.31 and 4.12
mg/g) was identified in both extracts. Spectrophotometrically determined total phenolics
contents were 126.08 and 125.33 mg gallic acid equivalents/g.
In the leaf dry dichloromethane extract, by LC-MS method, small amounts of
furanocoumarins isopimpinellin and bergapten were detected (totally 0.22 mg/g of dry
extract). Their presence was also previously shown (3). In the flower extract, besides these
two, six more furanocoumarins were identified; all present in small amounts (totally 20.07
mg/g). The most abundant was bergapten (4.84 mg/g), followed by byakangelicol (3.29
mg/g).
Total antioxidant (FRAP values 1.08 and 0.94 mmol Fe2+/g) and antiradical activities
(DPPH SC50 values 64.10 and 64.77 μg/mL) of the leaf and flower dry methanol extracts were
correlated with their total phenolics contents. Anti-DPPH activities of the dry
dichloromethane extracts were expectedly lower (SC50 values 636.19 and 790.20 μg/mL).
Heracleum sibiricum leaves and flowers represent new sources of compounds with
known antioxidant activity.

AB  - Kritski origano, Origanum dictamnus L. (Lamiaceae), je endemična biljka grčkog ostrva
Krit. Komitet za biljne lekovite proizvode Evropske agencije za lekove (EMA/HMPC) izdao je
EU monografiju za tradicionalnu primenu herbe kritskog origana, Origani dictamni herba.
Prema ovoj monografiji usitnjena herba se koristi oralno u obliku čaja (infuza) za
ublažavanje kašlja povezanog sa prehladom i za simptomatsko ublažavanje blagog
gastrointestinalnog diskomfora, kao i dermalno u obliku infuza ili dekokta za tretman manjih
inflamacija kože i modrica. U Evropskoj farmakopeji (Ph. Eur.) za sada ne postoje
monografije za ovu biljnu drogu i njeno etarsko ulje.
Cilj ovog rada bio je ispitivanje hemijskog sastava etarskog ulja izolovanog iz
komercijalnog uzorka herbe kritskog origana poreklom iz Grčke, kao i procena njegove
antiradikalske aktivnosti.
Etarsko ulje je izolovano iz herbe destilacijom vodenom parom u aparaturi po
Clevenger-u, prema postupku Ph. Eur. Prinos etarskog ulja iznosio je 1,51% V/m, tj. 1,46%
m/m. Hemijski sastav etarskog ulja analiziran je gasnom hromatografijom sa FID i MS
detekcijom (GC-FID i GC-MS). Identifikovane su 42 komponente, koje su činile 94,6% sastava
etarskog ulja. Procentualno najveći udeo u etarskom ulju činili su oksidovani monoterpeni
(58,8%; 9 jedinjenja), a sledili su monoterpenski ugljovodonici (27,4%; 12 jedinjenja),
seskviterpenski ugljovodonici (5,6%; 12 jedinjenja) i oksidovani seskviterpeni (2,3%; 6
jedinjenja). Glavna komponenta etarskog ulja bio je monoterpenski fenol karvakrol (51,4%),
dok su po količini sledili monoterpenski ugljovodonici p-cimen (14,3%) i γ-terpinen (9,3%).
Dobijeni rezultati bili su u skladu sa literaturnim podacima, pri čemu je u slučaju uzorka
analiziranog u ovom radu, prinos etarskog ulja bio veći od prethodno publikovanih vrednosti
(1, 2).
Antiradikalska aktivnost izolovanog etarskog ulja ispitana je spektrofotometrijskim
DPPH testom. Stepen antiradikalske aktivnosti je rastao linearno sa povećanjem
koncentracije etarskog ulja, pri čemu je koncentracija u kojoj je etarsko ulje inhibiralo 50%
DPPH radikala (SC50) iznosila 141,77 μg/mL. Značajan anti-DPPH potencijal etarskog ulja
herbe kritskog origana može se barem delom objasniti velikim udelom karvakrola, čiji je
antiradikalski potencijal ranije pokazan (3).
Rezultati sprovedenih hemijskih ispitivanja mogu biti od značaja za buduće
definisanje parametara farmaceutskog kvaliteta droge Origani dictamni herba i njenog
etarskog ulja.

for this herbal drug and its essential oil do not exist for now.
The aim of this work was to investigate chemical composition of the essential oil
obtained from a commercial sample of Cretan dittany herb and to evaluate its antiradical
activity.
The essential oil was isolated from the herb by hydrodistillation in a Clevenger‐type
apparatus, according to procedure given in Ph. Eur. The yield was 1.51% V/w, i.e. 1.46%
w/w. Chemical composition of the essential oil was analyzed by gas chromatography with
FID and MS detection (GC-FID and GC-MS). A total of 42 components were identified,
comprising 94.6% of the composition of the essential oil. The dominant were oxygenated
monoterpenes (58.8%; 9 compounds), followed by monoterpene hydrocarbons (27.4%; 12
compounds), sesquiterpene hydrocarbons (5.6%; 12 compounds) and oxygenated
sesquiterpenes (2.3%; 6 compounds). The main component of the essential oil was
monoterpene phenol carvacrol (51.4%), followed by monoterpene hydrocarbons p-cymene
(14.3%) and γ-terpinene (9.3%). Obtained results were in accordance with the literature
data; it should be noted that in the case of the sample analyzed in this work, the essential oil
yield was higher than previously published values (1, 2).
The antiradical activity of the essential oil was investigated by spectrophotometric
DPPH test. The percentage of antiradical activity increased linearly with the increase of
essential oil concentration. The concentration at which the essential oil inhibited 50% DPPH
radicals (SC50) was 141.77 μg/mL. Significant anti-DPPH potential of the essential oil of
Cretan dittany herb can be at least partly explained by the presence of high quantity of
carvacrol, which antiradical potential was demonstrated previously (3).
The results of performed chemical investigations may be important for defining
pharmaceutical quality parameters of the herbal drug Origani dictamni herba and its
essential oil in the future.

Krit. Komitet za biljne lekovite proizvode Evropske agencije za lekove (EMA/HMPC) izdao je
EU monografiju za tradicionalnu primenu herbe kritskog origana, Origani dictamni herba.
Prema ovoj monografiji usitnjena herba se koristi oralno u obliku čaja (infuza) za
ublažavanje kašlja povezanog sa prehladom i za simptomatsko ublažavanje blagog
gastrointestinalnog diskomfora, kao i dermalno u obliku infuza ili dekokta za tretman manjih
inflamacija kože i modrica. U Evropskoj farmakopeji (Ph. Eur.) za sada ne postoje
monografije za ovu biljnu drogu i njeno etarsko ulje.
Cilj ovog rada bio je ispitivanje hemijskog sastava etarskog ulja izolovanog iz
komercijalnog uzorka herbe kritskog origana poreklom iz Grčke, kao i procena njegove
antiradikalske aktivnosti.
Etarsko ulje je izolovano iz herbe destilacijom vodenom parom u aparaturi po
Clevenger-u, prema postupku Ph. Eur. Prinos etarskog ulja iznosio je 1,51% V/m, tj. 1,46%
m/m. Hemijski sastav etarskog ulja analiziran je gasnom hromatografijom sa FID i MS
detekcijom (GC-FID i GC-MS). Identifikovane su 42 komponente, koje su činile 94,6% sastava
etarskog ulja. Procentualno najveći udeo u etarskom ulju činili su oksidovani monoterpeni
(58,8%; 9 jedinjenja), a sledili su monoterpenski ugljovodonici (27,4%; 12 jedinjenja),
seskviterpenski ugljovodonici (5,6%; 12 jedinjenja) i oksidovani seskviterpeni (2,3%; 6
jedinjenja). Glavna komponenta etarskog ulja bio je monoterpenski fenol karvakrol (51,4%),
dok su po količini sledili monoterpenski ugljovodonici p-cimen (14,3%) i γ-terpinen (9,3%).
Dobijeni rezultati bili su u skladu sa literaturnim podacima, pri čemu je u slučaju uzorka
analiziranog u ovom radu, prinos etarskog ulja bio veći od prethodno publikovanih vrednosti
(1, 2).
Antiradikalska aktivnost izolovanog etarskog ulja ispitana je spektrofotometrijskim
DPPH testom. Stepen antiradikalske aktivnosti je rastao linearno sa povećanjem
koncentracije etarskog ulja, pri čemu je koncentracija u kojoj je etarsko ulje inhibiralo 50%
DPPH radikala (SC50) iznosila 141,77 μg/mL. Značajan anti-DPPH potencijal etarskog ulja
herbe kritskog origana može se barem delom objasniti velikim udelom karvakrola, čiji je
antiradikalski potencijal ranije pokazan (3).

definisanje parametara farmaceutskog kvaliteta droge Origani dictamni herba i njenog
etarskog ulja., Cretan dittany, Origanum dictamnus L. (Lamiaceae), is an endemic species from the
Greek island of Crete. The Committee on Herbal Medicinal Products of the European
Medicines Agency (EMA/HMPC) adopted EU monograph on traditional use of Cretan dittany
herb, Origani dictamni herba. According to this monograph, comminuted herb is used orally
as herbal tea (infusion) for the relief of cough associated with cold and for mild
gastrointestinal disorders, as well as cutaneously as infusion or decoction for the treatment
of minor skin inflammations and bruises. European Pharmacopoeia (Ph. Eur.) monographs

AB  - INTRODUCTION:
Pastinaca sativa subsp. sativa L., Apiaceae (parsnip) is cultivated mainly in the temperate regions of the world because of its edible root. The roots of the best quality are obtained from the plants from the first year, in which this biennial plant usually forms only leaf rosette. In the second year, flowering stems emerge (the plant is cultivated for two years in order to obtain fruits for reproduction). Wild-growing P. sativa subsp. urens (Req. ex Godr.) Čelak. is widely distributed in Europe and P. hirsuta Pančić is endemic in the central part of the Balkan Peninsula (east Serbia, North Macedonia and south and west Bulgaria).

OBJECTIVES:
To investigate and compare the composition of the essential oils obtained from roots, leaves, stems, flowers and fruits of cultivated P. sativa subsp. sativa (from the first and/or the second year) and wild-growing P. sativa subsp. urens and P. hirsuta from Serbia.

METHOD / DESIGN:
Essential oils were isolated from dried and comminuted plant material by hydrodistillation using Clevenger-type apparatus for 2.5 h. The composition of essential oils was determined by GC-FID and GC-MS and analyzed using multivariate statistical methods: principal component analysis (PCA), non-metric multidimensional scaling (nMDS) and unweighted pair-group arithmetic averages clustering (UPGMA).

RESULTS:
Twenty-nine parsnip essential oils were investigated: 11 P. sativa subsp. sativa oils (from four localities; the oils of roots and leaves from both the first and the second year, and of the other organs from the second year), 10 P. sativa subsp. urens oils (from two localities) and eight P. hirsuta oils (from one locality, collected in two different years). Pastinaca sativa subsp. sativa
roots from the first year provided the highest oil yields (0.51-0.77%, w/w). The roots of this taxon from the second year (0.02%), and the roots of other investigated Pastinaca taxa (0.10-0.14%) had notably lower oil yields. Regarding other plant organs, high oil yields were generally obtained for fruits (1.40-3.90%) and flowers (0.43-0.93%), and low oil yields for leaves (0.07-0.16%) and stems (0.03-0.13%).
In general, 13 to 53 compounds were identified in the essential oils; identified components accounted for 89.4-98.6% of the oils. Phenylpropanoid myristicin was the most abundant in the root essential oils of both investigated P. sativa subspecies (39.7-82.5%). It is interesting to note that the oil of P. sativa subsp. sativa roots from the first year also contained high amounts of terpinolene (14.8-28.7%), which significantly decreased in the oil of this taxon from the second year (1.2%). In P. hirsuta root oils another phenylpropanoid apiole (30.9 and 25.8%) was dominant and the quantities of myristicin were somewhat lower (11.6 and 20.3%). Cultivated P. sativa subsp. sativa leaf essential oils were dominated by myristicin (42.8 and 41.4%) and in the leaf oils of wild-growing parsnips (P. sativa subsp. urens and P. hirsuta), γ-palmitolactone was the most abundant
(22.6-47.5%). Additionally, the leaf oils of both investigated P. sativa subspecies contained significant amounts of sesquiterpenes (36.0-46.2%), e.g. (E)-β-farnesene (13.8-22.4%). Compared with the leaf oils, corresponding stem oils were qualitatively similar. However, in the stem oils, the contents of sesquiterpenes were lower [e.g. (E)-β-farnesene 4.9-14.4% in P. sativa oils] and the contents of myristicin (64.9 and 63.3% in P. sativa subsp. sativa oils) and γ-palmitolactone (50.6-60.4% in wild-growing parsnips oils) were higher. The flower and fruit essential oils were dominated by aliphatic esters. The most abundant in P. hirsuta oils were hexyl butanoate (61.9% in the flower oil; 22.0 and 58.4% in the fruit oils) and hexyl hexanoate (17.0% in the flower oil; 59.8 and 29.1% in the fruit oils), and in the oils of both P. sativa subspecies the dominant was octyl butanoate (26.1-31.4% in the flower oils; 53.6-79.0% in the fruit oils). In PCA and nMDS analyses of the oils (except fruit oils), the separation of all three investigated Pastinaca taxa was noticed. The same relations were observed in UPGMA analyses of the leaf, stem and flower oils. In the case of statistical analysis of the fruit oils and UPGMA analysis of the root oils, the samples of two subspecies of P. sativa were grouped together.

CONCLUSIONS:
Wild-growing parsnips are equally interesting sources of essential oils as cultivated parsnip. Locality and year of collection did not significantly influence relations among taxa observed in multivariate statistical analysis.

AB  - INTRODUCTION:
Cultivated parsnip (Pastinaca sativa subsp. sativa L., Apiaceae) root is a well-known vegetable, common ingredient of soups, stews, salads, casseroles etc. Besides, its leaves and young shoots can be added to soups and fruits are used as a condiment. Furthermore, young shoots of wild-growing parsnips, e.g. P. sativa subsp. urens (Req. ex Godr.) Čelak., are consumed pickled
or in salads or soups and it is considered that their essential oil acts as a natural preservative.

OBJECTIVES:
To investigate and compare the antimicrobial activity of the essential oils obtained from the roots, leaves, stems, flowers and fruits of cultivated P. sativa subsp. sativa and wild-growing P. sativa subsp. urens collected in Serbia. Furthermore, the most active essential oil constituents (against the most susceptible microorganisms) were predicted in silico.

METHOD / DESIGN:
Minimum inhibitory concentrations (MICs) and minimum bactericidal/fungicidal concentrations (MBCs/MFCs) of the essential oils (isolated by hydrodistillation using Clevenger-type apparatus) were determined by microdilution method against three Gram-positive bacteria: Staphylococcus aureus ATCC 11632, Bacillus cereus clinical isolate and Listeria monocytogenes NCTC 7973, three Gram-negative bacteria: Escherichia coli ATCC 25922, Salmonella Typhimurium ATCC 13311 and Enterobacter cloacae ATCC 35030, three Candida standard strains: C. albicans ATCC 10231, C. tropicalis ATCC 750 and C. parapsilosis ATCC 22019, and three Candida isolates from oral cavity: C. albicans 475/15, C. krusei H1/16 and C. glabrata 4/6/15. Pharmacokinetic properties of the compounds present in at least one oil in the quantity ≥ 1% (determined by GC-FID and GC-MS) were initially evaluated using SwissADME web tool and molecular docking was performed using AutoDock Vina 1.1.2 (interactions were visualized using Discovery Studio Visualizer 2019).

RESULTS:
All the investigated essential oils of the two Pastinaca sativa subspecies were able to reduce the growth of different tested Candida strains (MIC range 0.25-2 mg/mL; MFC range 0.5-4 mg/mL). The most promising activity was observed for both root oils (MIC range 0.25-1 mg/mL; MFC range 0.5-2 mg/mL). Among investigated Candida strains, C. parapsilosis strain was the most sensitive to these essential oils (MIC range 0.25-1 mg/mL; MFC range 0.5-2 mg/mL). The antibacterial activity of the tested essential oils was lower compared to their anticandidal potential (MIC range 1-4 mg/mL; MBC range 2-8 mg/mL). Thirty compounds were present in at least one oil in the quantity ≥ 1%. Estimation of pharmacokinetic properties using SwissADME tool suggested that 23 of these compounds are inhibitors of some of the cytochrome P450 system isoenzymes. This fact led
to assumption that they could also act against fungal sterol 14α-demethylase (CYP51), which is a common target of antifungal drugs (e.g., ketoconazole). Thus, the compounds (3D structures downloaded from PubChem) were docked to the active site of this enzyme (downloaded from Protein Data Bank, PDB code 5TZ1). The highest affinities were predicted for sesquiterpenes
caryophyllene oxide, (E)-caryophyllene, germacrene D, α-copaene, β-bourbonene and δ-cadinene (free binding energies from -9.4 to -8.7 kcal/mol; ketoconazole -11.6 kcal/mol). These compounds were present in somewhat lower quantities in the essential oils (≤ 9.9%). For dominant compounds of the tested essential oils, e.g. myristicin, γ-palmitolactone and octyl butanoate a bit lower affinities were predicted (free binding energies from -7.3 to -5.8 kcal/mol). Tested compounds mostly docked near the heme of the enzyme and formed hydrophobic interactions with the amino acid residues of the active site. According to SwissADME tool, four of five most active compounds have low absorption from gastrointestinal tract and higher skin permeation value, while caryophyllene oxide and three dominant compounds have high absorption and lower skin permeation value (similarly to ketoconazole).

CONCLUSIONS:
Investigated parsnips represent sources of essential oils and compounds with anticandidal activity.

Among investigated Candida strains, C. parapsilosis strain was the most sensitive to these essential oils (MIC range 0.25-1 mg/mL; MFC range 0.5-2 mg/mL). The antibacterial activity of the tested essential oils was lower compared to their anticandidal potential (MIC range 1-4 mg/mL; MBC range 2-8 mg/mL). Thirty compounds were present in at least one oil in the quantity ≥ 1%. Estimation of pharmacokinetic properties using SwissADME tool suggested that 23 of these compounds are inhibitors of some of the cytochrome P450 system isoenzymes. This fact led
to assumption that they could also act against fungal sterol 14α-demethylase (CYP51), which is a common target of antifungal drugs (e.g., ketoconazole). Thus, the compounds (3D structures downloaded from PubChem) were docked to the active site of this enzyme (downloaded from Protein Data Bank, PDB code 5TZ1). The highest affinities were predicted for sesquiterpenes
caryophyllene oxide, (E)-caryophyllene, germacrene D, α-copaene, β-bourbonene and δ-cadinene (free binding energies from -9.4 to -8.7 kcal/mol; ketoconazole -11.6 kcal/mol). These compounds were present in somewhat lower quantities in the essential oils (≤ 9.9%). For dominant compounds of the tested essential oils, e.g. myristicin, γ-palmitolactone and octyl butanoate a bit lower affinities were predicted (free binding energies from -7.3 to -5.8 kcal/mol). Tested compounds mostly docked near the heme of the enzyme and formed hydrophobic interactions with the amino acid residues of the active site. According to SwissADME tool, four of five most active compounds have low absorption from gastrointestinal tract and higher skin permeation value, while caryophyllene oxide and three dominant compounds have high absorption and lower skin permeation value (similarly to ketoconazole).

CONCLUSIONS:
Investigated parsnips represent sources of essential oils and compounds with anticandidal activity.",

AB  - The composition of leaf and flower essential oils of eight Heracleum taxa (populations collected in Serbia, Montenegro, North Macedonia and Slovenia) was statistically analyzed to evaluate its chemosystematic significance. Investigated taxa included H. orphanidis and the representatives of H. sphondylium group: H. sphondylium, H. sibiricum, H. montanum, H. ternatum, H. pyrenaicum subsp. pollinianum, H. pyrenaicum subsp. orsinii and H. verticillatum. Hydrodistilled essential oils were analyzed by GC–FID and GC–MS. Chemosystematic significance was evaluated using multivariate statistics: principal component analysis (PCA), non-metric multidimensional scaling (NMDS) and unweighted pair-group arithmetic averages clustering (UPGMA). Statistical analyses included our previously published data on the composition of essential oils of eight leaf and three flower samples, as well as the data on the composition of the oils of additional eight leaf and five flower samples obtained in the current work. Leaf and flower essential oils of H. sphondylium group members were dominated by various sesquiterpenes, phenylpropanoids and/or monoterpenes. Heracleum orphanidis leaf and flower essential oils were rich in aliphatic esters, mostly octyl acetate. Statistical analysis of the composition of leaf essential oils, as well as of flower oils, demonstrated the grouping of investigated populations of these Heracleum taxa according to their systematics, i.e., separation of H. orphanidis from the representatives of H. sphondylium group, and grouping of H. pyrenaicum subspecies within this group. Morphologically related H. sibiricum and H. ternatum were closely located in PCA and NMDS and in UPGMA even shared the same cluster.

AB  - According to current EU monograph of the Committee on Herbal Medicinal Products of
European Medicines Agency (EMA/HMPC) for ginkgo leaf, Ginkgonis folium (Ginkgo biloba,
Ginkgoaceae), herbal medicines prepared from refined and quantified dry extract of ginkgo leaf
are used for the improvement of (age-associated) cognitive impairment and of quality of life in
mild dementia. It was demonstrated in clinical trials that long-term use of the extract is effective
mainly in patients more than 50 years old. The precise mode of action is not known. According
to Ph. Eur., the extract should contain 22.0-27.0% of flavonoids, 2.8-3.4% of ginkgolides A, B
and C, and 2.6-3.2% of bilobalide, which are active constituents, and maximum 5 ppm of
ginkgolic acids, which are potential allergens. These herbal medicines are characterized by
corresponding posology, duration of use, contraindications, special warnings, and precautions for
use, interactions and possible undesirable reactions.
