摘要
本实验从雷公藤多甙中又分离出３个三萜类化合物Ｔ_（１６）、Ｔ_（１７）、Ｔ_（１８）经光谱数据分析和制备已知化合物的衍生物，确定了它们的分子结构，即Ｔ_（１６）是ｓａｌａｓｐｅｒｍｉｃａｃｉｄ，Ｔ_（１７）为雷公藤内酯乙（ｗｉｌｆｏｒｌｉｄｅＢ），Ｔ_（１８）是一个新的齐墩果烯类三萜酸化合物，命名为雷藤三萜酮酸Ａ（ｔｒｉｐｔｏｔｒｉｔｅｒ－ｐｅｎｏｎｉｃａｃｉｄＡ），化学名３－ｏｘｏ－２２（－ｈｙｄｒｏｘｙ－△￣（１２）－ｏｌｅａｎｅｎ－２９－ｏｉｃａｃｉｄ。
Three more triterpenoids were isolated from total glucosides of tripterygium wilfordii(TⅡ).T16 and T17 were identified as salaspermic acid and as wilforlide B.T18 was a new compound.The structure of T18 was determined,as 3-oxo-22)α-hydroxy-△ 12-oleanen-29-oic acid by detail spectroscopic and chemical analysis,and named triptotriterpenonic acid A.
