Abstract
The new triterpene glycoside cucumarioside G2 [1] has been isolated from the sea cucumber Eupentacta fraudatrix. Glycoside 1 is the first triterpene glycoside with the 23,24,25,26,27-pentanorlanostane type of aglycone. Its structure has been established by chemical transformations as well as 13C- and 1H-nmr, eims, and liquid sims studies.
摘要
新的三萜糖苷海参皂苷G2 [1]已从海参伪刺参中分离出来。糖苷1是首个具有23,24,25,26,27-五降羊毛甾烷型苷元的三萜糖苷。其结构已通过化学转化以及13C和1H核磁共振、电子轰击质谱和液相二次离子质谱研究得以确定。
