The chemistry of bryophytes is not well known. The available data indicate interesting chemical constitutions of some bryophyte species, i.e., ac- tive and new compounds are to be found within bryophytes, especially liver- worts. In this study, one liverwort and two moss species were studied: Lunu- laria cruciata (L.) Dumort, Brachytheciastrum velutinum (Hedw) Ignatov & Huttunen and Kindbergia praelonga (Hedw) Ochyra. The phenolic compo- sitions of these bryophyte species have not hitherto been reported. Their metha- nolic extracts were analyzed by reversed-phase HPLC, coupled to a diode-array detector (DAD). Luteolin-7-O-glucoside and quercetin were found in the L. cruciata extract. The extract obtained from B. velutinum contained four phe- nolic acids (4-O-caffeoylquinic, 5-O-caffeoylquinic, caffeic and ellagic acids) and three flavonoids (apigenin-7-O-glucoside, luteolin and apigenin). The K. praelonga extract was characterized by the presence of several phenolic acids and their derivatives (4-O-caffeoylquinic, 5-O-caffeoylquinic, caffeic, p-cou- maric, ferulic and ellagic acids, and caffeic and p-coumaric acid derivatives) and three flavonoids (apigenin-7-O-glucoside, luteolin, apigenin and an un- identified flavanone).
