白花油麻藤化学成分研究

Chemical constituents of stem barks of Mucuna birdwoodiana

目的:研究白花油麻藤Mucuna birdwoodiana藤茎的化学成分。方法:采用柱色谱方法分离化合物,采用谱学方法鉴定其结构。结果:分离并鉴定了11个化合物。3′-methoxycoumestrol(1),芒柄花素(formononetin,2),染料木素(genisten,3),8-甲雷杜辛(8-O-methylretusin,4),7,3′-二羟基-5′-甲氧基异黄酮(5),大黄酚(chrysophanol,6),丁香脂素(syringaresinol,7),表木栓醇(epifriedelanol,8),羽扇豆醇(lupeol,9)。结论:除化合物2,3,8,9外,以上化合物均为首次从该属植物分得。

Eleven compounds were isolated from the stem bark of Mucuna birdwoodiana.Their structures were elucidated by various spectral analyses and identified as 3′-methoxycoumestrol（1）,formononetin（2）,genisten（3）,8-O-methylretusin（4）,7,3′-dihydroxy-5′-methoxyisoflavone（5）,chrysophanol（6）,syringaresinol（7）,epifriedelanol（8）,lupeol（9）,respectively.All compounds except 2,3,8 and 9 were isolated from the genus for the first time.
