AB  - In the present research, the chemical composition of aerial parts of cultivated citral chemotype of Thymus pannonicus All. (Lamiaceae), growing at different soil conditions was studied. Two plant lineages were unfertilized or treated using either nitrogen or phosphorus fertilizers at different concentration levels. Essential oil (EO) content, EO composition, and composition of hydromethanol extracts (MEs) were compared to the results obtained for wild growing plants in order to evaluate the potential of T. pannonicus for its industrial production. EO content (%, V/m) in cultivated samples varied between 0.32-0.75% and 0.62-1.05% within two examined lineages, whereas the herbs from the natural habitat contained 0.49-1.29% of EO. GC-FID/MS analysis showed that citral, i.e. mixture of isomers geranial and neral, was the most abundant constituent in all EOs (51.90-81.96%). HPLC analysis revealed that total caffeic acid derivatives, with rosmarinic acid (RA) as the most abundant compound in all extracts, as well as total apigenin glycosides contents were significantly higher in the extracts originating from the cultivated herbs (112.15-184.94 mg/g and 5.08-15.29 mg/g, respectively), in comparison to the extracts of the herbs from the natural habitats (67.61-98.75 mg/g and 1.17-1.32 mg/g). In general, the composition of cultivated herbs varied less than that of samples originating from natural habitats, indicating that controlled cultivation of citral chemotype of T. pannonicus can provide herbal drug with favourable characteristics. Only minor differences were observed between cultivated samples treated with different fertilizers.

AB  - Panonian thyme (Thymus pannonicus All. Lamiaceae) is distributed in central and eastern
Europe, over dry meadows, grasslands and rocks. In Serbia, it can be found mostly in Vojvodina
province. Reference data reveals high variability in the composition of wild‐growing pannonian
thyme. A number of chemotypes (e.g. thymol and citral) were confirmed. In Serbia, a stable
population of citral chemotype has been found at Mt. Vršačke planine only. In southern Banat,
dried herb of this chemotype is used to make tasty and refreshing herbal teas with peculiar and
pleasant lemon‐like scent; also, against some respiratory and gastrointestinal disorders. This
provided the ground for further and detailed investigations on this plant species from Mt.
Vršačke planine.
By chromatographic analysis (GC FID/MS; HPLC), polymorphism within wild populations
of this species was studied, as well as dominant ecological factors that influenced their
morphologic, anatomic and chemical properties. Antimicrobial, antioxidant, antitumour and
hepatoprotective activity were also tested. Planned cultivation was attempted and lines with
desirable traits were chosen. Parameters of quality for pannonian thyme herb as a new herbal
raw material were defined.
The results indicate that pannonian thyme from Mt. Vršačke planine could be considered
as a pleniful source of herbal raw material rich in citral. Principal constituents of polar extracts of
wild growing pannonian thyme were phenolic acids (rosmarinic, salvianolic) and flavonoids
(luteolin and apigenin glucuronides). Aqueous extract expressed moderate antioxidant effect in
vivo, along with a significant decrease of lipid peroxidation intensity and preservation of
physiological levels of glutathione. Against Ehrlich ascites tumor cells in mice, aqueous extract
expressed significant cytotoxic activity, through prooxidant effect that induced apoptosis.
Significant antimicrobial activity against tested microorganisms was observed; in particular,
against Candida albicans. Essential oil and methanolic extract expressed remarkable inhibitory
activity against clinical strains of Helicobacter pylori resistant to metronidazol and
claritromycine. Finally, a variety with desired technological characteristics was bred, yielding
superior biomass quantity, as well as higher and more stabile essential oil contents in
comparison to wild‐growing plants.
Pannonian thyme citral chemotype appeared to be a plentiful biological source of herbal
substance Thymi pannonici herba. Owing to high contents of polyphenols and essential oil rich in
citral, as well as to expressed antioxidant, antimicrobial and antitumor activity, it is a potentially
new herbal raw material that could be used in contemporary phytotherapy.

AB  - Deodorised water extracts of aromatic plants are obtained as by-products of essential oil isolation and usually discarded as waste. However, phytochemical composition of these extracts encourages their further utilization as food additives or functional food ingredients. In this study we investigated phytochemical composition, antioxidant and in vivo antiproliferative activity of deodorised water extract of Thymus pannonicus All. (DWE). HPLC analysis revealed rosmarinic acid (RA) (71.11 +/- 1.54 mg/g) as the most abundant constituent of the extract, followed by salvianolic acid H (14.83 +/- 0.79 mg/g, calculated as RA). DWE exhibited pronounced antioxidant activity in vitro, in FRAP and DPPH tests (FRAP value: 7.41 mmol Fe/g and SC50: 3.80 mu g/g, respectively). Using the model of Ehrlich carcinoma cells in mice that were treated with DWE prior, at the time, and after tumour cells implantation, the tumour growth suppression and redox status of malignant cells (i.e., activities of antioxidant enzymes, level of glutathione and intensity of lipid peroxidation) were followed. DWE applied as pretreatment caused disturbance of antioxidant equilibrium as well as apoptosis/necrosis of up to 90% EAC cells. Results obtained in the present study revealed chemopreventive potential and possibility of T. pannonicus DWE usage. High content of RA and other phenolic compounds explains, at least in part, the observed effects.

AB  - Hungarian thyme (Thymus pannonicus All., Lamiaceae) is an aromatic herb used as traditional remedy, a refreshing beverage and a food aromatizer. Herbal teas, i.e., infusions, of Hungarian thyme from eight localities in Serbia were analyzed regarding their polyphenolic and volatile composition, and tested for their antioxidant and antimicrobial activity. The total polyphenolics content, determined by the Folin-Ciocalteu method, ranged from 1122.25 to 1979.93 mg gallic acid/L. HPLC analysis revealed rosmarinic acid (367.42-1199.47 mg/L) and luteolin glucuronides as the main polyphenolics. The volatile fractions of the infusions, analyzed by static headspace extraction coupled with GC and GC-MS analyses, contained citral, 3-octanone, 1-octen-3-ol, linalool and 1,8-cineole as the dominant constituents. The antioxidant activity of the infusions was examined through the ferric reducing antioxidant power (FRAP) (68.09-124.58 mmol Fe2+/L) and the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical tests (SC50 1.32-2.96 mu L/mL). The antimicrobial activity was tested by the broth microdilution method against standard strains of Gram(+) Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis and Enterococcus faecalis and Gram(-) bacteria Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa, and one strain of yeast Candida albicans. The infusions inhibited microbial growth in the tested concentration range (31.25-500.00 mu L/mL) and the strongest activity was exhibited against the strain of C. albicans (MIC 31.25-62.50 mu L/mL). The antioxidant and antimicrobial properties of the infusions were, to some extent, in correlation with the composition and content of the polyphenolic compounds, whereas the volatiles noticeably influenced the exhibited antimicrobial activity.

AB  - The volatile fraction of the leaves of Thymus pannonicus All. (Lamiaceae) was analyzed by headspace extraction followed by GC-FID and GC-MS analysis. The different headspace profiles were recognized, with citral and with monoterpene hydrocarbons as dominant compounds. In addition, the determination of Cr, Co, Ni, Mo, Cu, Zn, Mn, Fe, Mg, Ca, K and Na was conducted by spectroscopic techniques (FAAS, GFAAS and ICP-OES). In order to evaluate the relationship between volatile organic compounds and metals, a chemometrics approach was applied. The data obtained by analysis of the headspace and elemental content were subjected to correlation analysis, factor analysis, principal component analysis and cluster analysis. A number of significant correlations of metals with plant volatiles were found. Correlation of Zn with citral, Mn with oxygenated monoterpenes and Mg with beta-bourbonene, could be explained by involvement of metals in the biosynthesis of volatile organic compounds.

AB  - Three populations of Thymus pannonicus grown in Serbia (one from northern and two from east Serbia) were examined for chemical composition of their essential oil. Thymus pannonicus is used in traditional medicine and it is collected by local people in the studied regions, hence the interest in composition of its essential oils. Three major groups of essential oil components were identified, such as monoterpene hydrocarbons, oxygenated monoterpene hydrocarbons and sesquiterpene hydrocarbons. Each of investigated populations showed its own chemotype, including: geranial (citral), alpha-pinene and germacrene-D. To best of our knowledge, this sesquiterpene hydrocarbon was reported as a major component in Thymus bracteosus only. In these populations the phenolic compounds thymol and carvacrol, considered as most frequent constituents of essential oil in Thymus taxa, haven't been found in significant quantities.
