Abstract From the roots, leaves and pods of Tephrosia pentaphylla three new 6-oxygenated rotenoids (dihydrostemonal, 9-demethyldihydrostemonal and 6-acetoxydihydrostemonal) were isolated and characterized. In addition six known rotenoids (villosin, sumatrol, rotenone, cis -12a-hydroxyrotenone, 6-hydroxyrotenone and α-toxicarol) and the flavanone obovatin were obtained. A similar analysis of the roots
摘要 从Tephrosia pentaphylla 的根、叶和豆荚中分离并表征了3 种新的6-含氧类胡萝卜素(dihydrostemonal、9-demethyldihydrostemonal 和6-acetoxydihydrostemonal)。此外,还获得了六种已知的类胡萝卜素(绒毛素、苏门答腊、鱼藤酮、顺式 -12a-羟基鱼藤酮、6-羟基鱼藤酮和 α-毒胡萝卜素)和黄烷酮 obovatin。对 T. fulvinervis 根的类似分析只产生了已知的类胡萝卜素(α-toxicarol、deguelin、munduserone、cis -12a-hydroxymunduserone)和常见的 pterocarpan (-)-maackiain。
