| Abstract: | A novel steroidal glycoside has been isolated from the starfish Protoreaster nodosus. The structure includes a 3β,5α,6β,8β,15α,24ξ-hexahydroxysteroidal moiety and a sugar moiety 2-0-methyl-β-D-xylopyranosyl-(1 → 2)-α-L-arabinofuranosyl] which is glycosidically attached at C-24 of the aglycone. |
