Abstract The phytochemical study of the alcoholic extract obtained from Bipinnula fimbriata (Poepp.) I.M.Johnst., allowed to isolate three metabolites, corresponding to the butanolide kinsenoside (1) and to two dihydrostilbene derivatives, which have been assigned as 3-methoxy-5-{2-[3-methoxy-2-(3-methylbut-2-en-1-yl)-phenyl]ethyl}phenol (2) and 4-[2-(3-hydroxy-5-methoxyphenyl)ethyl]-2-(3-methylbut-2-en-1-yl)phenol, also named cannabistilbene I (3). The occurrence of these compounds is consistent with the current classification of the genus and allowed to point out some chemotaxonomic considerations.

二氢芪衍生物加上来自稀有物种 Bipinnula fimbriata (Poepp.) IMJohnst 根的人参皂苷。

摘要 对从 Bipinnula fimbriata (Poepp.) IMJohnst. 获得的酒精提取物进行的植物化学研究允许分离三种代谢物，对应于丁内酯人参皂苷 (1) 和两种二氢芪衍生物，它们已被指定为 3-甲氧基-5- {2-[3-甲氧基-2-(3-甲基丁-2-烯-1-基)-苯基]乙基}苯酚(2)和4-[2-(3-羟基-5-甲氧基苯基)乙基]- 2-(3-methylbut-2-en-1-yl) 苯酚，也称为大麻二烯 I (3)。这些化合物的出现与目前的属分类一致，并允许指出一些化学分类学方面的考虑。
