A new triterpene glycoside,leucospilotaside C,along with two known saponin,was isolated from sea cucumber Holothuria leucospilota collected from the South China Sea,and its structure was elucidated as 3-O-[4’-O-sodiumsulfate-β-D-xylopyranosyl]- holosta-22,25-epoxy-9-ene-3β,12α,17α-triol (1) by extensive spectroscopic analysis and chemical methods.The glycosides have the same triterpene aglycone,but differ in the oligosaccharide moieties.
