Chemosystematic investigations on phenolic compounds of some Cerastium taxa (Caryophyllaceae) from Balkan Peninsula
Апстракт
The genus Cerastium L., with ca. 200 species primarily distributed in the Palaearctic, is one of the
largest genus in the family Caryophyllaceae. The type subsection of the genus (subsect. Cerastium) encompasses between 55 and 60 perennial species. The chorological analyses had shown that the present
centres of diversity and endemism both of genus (34 species) and the type subsection (19 species) are
located in the area of Balkan countries.
Giving that subsect. Cerastium represents an intricate and highly variable taxonomic group, we performed a HPLC analysis of phenolic compounds (flavonoids and phenolic acids) in methanol extracts of the flowering herbs of 15 taxa (including 9 species) from 17 Balkan localities in order to elucidate their chemotaxonomic differentiation. The HPLC chromatograms of 17 samples showed presence of 43 compounds grouped into 5 classes: O-glycosides of apigenin, C-glycosides of apigenin and luteolin, flavonoid aglycones and phenolic acids. Among the menti...oned phenolic compounds we have identified: apigenin 7-O-glucoside, apigenin 7-O-rutinoside, vitexin, vitexin 2"-O-ramnoside, homoorientine and free apigenin. Apigenin O- and C-glycosides were detected in all samples. None of the compounds or compound groups has a statistically important impact on subspecies differentiation.
Among the studied taxa, C. dinaricum G. Beck & Szysz. particularly stands out, as it differs by a significantly smaller number of compounds and the lack of C-glycosides of luteolin. The second isolated
group includes C. banaticum (Rochel) Steudel and C. arvense L., characterized by presence of phenolic acids, which were not registered in other samples. The third (C. alpinum L., C. malyi (Georgiev) Niketić
and C. eriophorum Kit.) and the fourth group (C. decalvans Schlosser & Vuk. , C. grandiflorum Waldst. & Kit. and C. candidissimum Correns) do not show great differences in composition of compounds.
