我国西南地区六种药用柴胡属植物地上部分的化学成分研究

Chemical Constituents of the Acrial Parts of Six Species of Bupleurum Genus Medicinally Used in South-west Region of China

对西南地区6种药用柴胡地上部分的化学成分进行了研究,得到8个黄酮和6个皂甙化合物。8个黄酮的甙元为槲皮素和异鼠李素,与北柴胡地上部分黄酮的甙元为山奈酚有所不同,可供柴胡属植物化学分类参考。

The chemical constituents of the aerial parts of six species of Bupleurum genus (B. kunmingense, B. polyclonum, B. wenchuanense, B. longicaule var. franchetii, B. rockii and B. chaishoui) medicinally used in south-west region of China have been investigated with the results of nobtaiing eight flavonoid compounds and six triterpenoid saponins. The aglycones of these eight flavonoid compounds are quercetin and isorhamnetin, which are different from the aglycones of the flavonoid compounds isolated from the aerial parts of B. chinense, the official species in Chinese Pharmacopoeia. In the latter case, the aglycone is kaempferol. This difference may be of chemotaxonomic value in Bupleurum genus.
