Abstract

Five prenylated flavonoids, 8-(1,1-dimethylallyl)genistein (1), 5,7,3',4'-tetrahydroxy-2',5'-di(3-methylbut-2-enyl)isoflavone (2), 5,7,3'-trihydroxy-2'-(3-methylbut-2-enyl)-4',5'-(3,3-dimethylpyrano)isoflavone (3), (2R)-5,2',4'-trihydroxy-8,5'-di(3-methylbut-2-enyl)-6,7-(3,3-dimethylpyrano)flavanone (4a) and (2S)-5, 2', 4'-trihydroxy-8,5'-di(3-methylbut-2-enyl)-6,7-(3,3-dimethylpyrano)flavanone (4b), were isolated from the roots of Moghania philippinensis. The structures of these compounds were determined on the basis of spectroscopic and chemical means.

摘要

从菲律宾葫芦茶的根中分离出了五种异戊烯基黄酮，分别为8-(1,1-二甲基烯丙基)染料木素(1)、5,7,3',4'-四羟基-2',5'-二(3-甲基丁-2-烯基)异黄酮(2)、5,7,3'-三羟基-2'-(3-甲基丁-2-烯基)-4',5'-(3,3-二甲基吡喃)异黄酮(3)、(2R)-5,2',4'-三羟基-8,5'-二(3-甲基丁-2-烯基)-6,7-(3,3-二甲基吡喃)黄烷酮(4a)和(2S)-5,2',4'-三羟基-8,5'-二(3-甲基丁-2-烯基)-6,7-(3,3-二甲基吡喃)黄烷酮(4b)。这些化合物的结构通过光谱和化学方法确定。
