Abstract

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) .
