Article abstract of DOI:10.1016/S0040-4039(00)88443-9

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-O-methyl-β-D-xylopyranosyl-(1-2)-α-L-arabinofuranosyl> which is glycosidically attached at C-24 of the aglycone.
