Two novel compounds representing two new classes of marine natural products have been isolated from Asterias forbesi together with several nucleosides and deoxynucleosides. The structures of the novel compounds have been determined by spectroscopic means: one, forbesin, a glycolipid, is shown to be 16-O-[.beta.-D-quinovopyranosyl-(1.fwdarw.2)-O-.beta.-D-quinovopyranosyl]eicosane-1-sodium sulfate and the other is the disodium salt of eicosane-1,16-disulfate.
