SYNOPSIS 

 

In this paper preliminary study of chemical constituents of three bryophyte species will be presented. Gametophytes of Polytrichum formosum, Eurhynchium hians (mosses) and Pellia endiviifolia (liverworth) have been collected in the native habitats in Petnica near Valjevo ( W. Serbia ). TLC technique was applied for the preliminary study of petroleum ether and methanol extracts of three investigated species.

According to this assay the presence of flavonoids (aglycones and glycosides) in all examined extracts was confirmed. In extracts of two species phenolic acids were detected. Besides, in the petroleum ether extract of all three species triterpenes were detected. Alkaloids were absent in the extracts of investigated bryophyte species.

SINOPSIS

  

PRILOG POZNAVANJU HEMIJSKOG SASTAVA BALKANSKIH BRIOFITA: FENOLNE KISELINE, FLAVONOIDI, TRITERPENI I ALKALOIDI

 

U ovom radu su dati preliminarni rezultati hemijskih konstituenata tri vrste briofita. Gametofiti Polytrichum formosum, Eurhynchium hians (mahovine) i Pellia endiviifolia (jetrenjača) su sakupljeni u prirodnim staništima okoline Valjeva (Zap. Srbija). Primenjena je TLC tehnika (tankoslojna hromatografija) u karakterisanju petroleimskog i metanolnog ekstrakta tri odabrane vrste.

Prisustvo flavonoida (aglikona i glikozida) je potvrdjeno u svim analiziranim ekstraktima. U ekstraktima dve vrste detektovane su fenolne kiseline. Osim toga u petroleumskom ekstraktu sve tri vrste detektovani su triterpeni. Alkaloidi nisi pronadjeni kod ni jedne od tri istraživane vrste.
