Five new triterpene bisglycosides, foetidinosides A (1), B (2), C (3), D (4) and E (5), including three of the cycloartane type, one of its derivative, and one of the lanostane type were isolated from the rhizomes of Cimicifuga foetida. Their structures were elucidated on the basis of spectroscopic data and chemical evidence. They were the first bisglycosides with acyclic side chains which were different from the typical triterpenes with side chains epoxidized with ring D in Cimicifuga species.
从 Cimicifuga foetida 的根茎中分离出了五种新的三萜双糖苷,即 foetidinosides A (1)、B (2)、C (3)、D (4) 和 E (5),其中包括三种环木菠萝烷类、一种其衍生物和一种羊毛甾烷类。根据光谱数据和化学证据阐明了它们的结构。它们是首批具有无环侧链的双糖苷类化合物,不同于 Cimicifuga 物种中具有环氧化环 D 侧链的典型三萜类化合物。
