可疑翼手参中的一个新三萜皂苷(英文)

A new triterpene glycoside from the sea cucumber Colochirous anceps

目的:寻找结构新颖的三萜皂苷类化合物。方法:采用多种色谱方法,对属于枝手目瓜参科的可疑翼手参体内成分进行了分离纯化;并采用多种光谱(IR,UV,ESI-MS,2D-NMR)和化学方法对所分离化合物的结构进行了确定。结果与结论:得到一个新的三萜皂苷类化合物,我们把该化合物命名为colochirosideA(1)。

Objective To search for triterpene glycoside with new structure. Methods We studied the sea cucumber Colochirous anceps belonging to the family cucumariidea with many chromatography methods and found a new sulfated triterpene glycoside, which structure was established by a combination of spectroscopic analysis (IR, UV, ESI-MS and 2D-NMR), chemical transformations and other chemical evidence. Results and Conclusion The new sulfated triterpene glycoside was isolated and named Colochiroside A (1) .
