Abstract:
A new triterpene glycoside (1) along with the known intercedenside B (2) was isolated from the sea cucumber Pseudocolochirus violaceus. Glycoside 1 was elucidated as 3-O-{6-O-sodiumsulfate-3-O-methyl-beta-D-glucopyranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-[beta-D-xylopyranosyl(1-->2)]-beta-D-quinovopyranosyl-(1-->2)-4-O-sodiumsulfate-beta-D-xylopyranosyl}-16beta-acetoxy-holosta-7, 24-diene-3beta-ol on the basis of extensive spectral studies and chemical evidence. Both the glycosides exhibited significant cytotoxicity against cancer cell lines MKN-45 and HCT-116.
