Abstract:
Two new flavan-4-ol glycosides, (2R,4S)-6,8-dimethyl-7-hydroxy-4'-methoxy-4,2''-oxidoflavan-5-O-beta-D-6''-O-acetyl-glucopyranoside (1) and (2R,4S)-5,7-O-beta-D-di-glucopyranosyloxy-4'-methoxy-6,8-dimethyl-4,2''-oxidoflavane (2), were isolated from the rhizomes of Abacopteris penangiana. Their structures were elucidated by spectroscopic methods. Compounds 1 and 2 showed significant anticancer activities against HeLa and L929 cell lines in vitro.
