Abstract

By repeated column chromatography on silica gel new glycosides have been isolated from the holothuriansAstichopus multifidus andStichopus chloronotus — astichoposide C and stichoposide C (I and II, respectively). Their structures have been studied with the aid of chemical and physicochemical methods. The complete structures of the glycosides have been established as 23(S)-acetoxy-3β-{4′-O-[O-(3-O-methyl-β-D-glucopyranosyl)-(1→3)-β-D-glucopyranosyl]-2′-O-[O-(3-O-methyl-β-D-glucopyranosyl)-(1→3)-O-β-D-xylopyranosyl-(1→4)-β-D-quinovopyranosyl]-β-D-xylopyranosyloxy}holosta-7,25-diene and -holost-7-ene.
