A new triterpene glycoside - cumarioside G1 - has been isolated from the Pacific Ocean holothurian Cucumaria fraudatrix.On the basis of physicochemical characteristics and the results of chemical transformations, its structure has been established as 16β-acetoxy-3β-3)-O-β-D-glucopyranosyl-(1->4)-β-D-quinovopyranosyl-(1->2)-(4-O-sulfato-β-D-xylopyranosyloxy)>holosta-7,24-diene.

Three polyhydroxylated steroids were isolated from the Far-Eastern starfish Hippasteria phrygiana collected from the Sea of Okhotsk and were characterized as a new glycoside phrygioside A, viz., sodium (20R, 24S)-3β,4β, 7α,8,15β,24-hexahydroxy-24-O-[3-O-methyl-β-D-xylopyranosyl- (1→2)-α-L-arabinofuranosyl]-5α-cholestan-6α-yl sulfate, its aglycone, and the already known marthasterone sulfate.
