Three new glycosides, D1, D2, and D3, have been isolated from the Far Eastern starfish Distolasterias nipon.They have been identified by chemical and physicochemical methods as 5α-cholestane3β,6α,8β,15β,24ξ-pentaol 3,24-di-O-β-D-xylopyranoside(I), 5α-cholest-22-ene-3β,6α,8β,15β,24ξ-pentaol 3,24-di-O-β-D-xylopyranoside (II), and 5α-cholestane-3β,6α,8β,15β,24ξ-pentaol 24-O-β-D-glucopyranoside 3-O-β-D-xylopyranoside (III).

Nine steroidal compounds including three new steroidal glycosides, viz., sodium (24S)-3,24-di-O-(β-D-xylopyranosyl)-5α-cholestane-3β, 6β,8,15α,24-pentol 15-sulfate (fuscaside A), (24S)-3,24-di-O-(β- D-xylopyranosyl)-5α-cholestane-3β,6β,8,15α,24-pentol (fuscaside B), and (22E,24R)-24-O-(β-D-xylopyranosyl)-5α-cholest-22- ene-3β,6α,8,15β,24-pentol (desulfated minutoside A); three previously known glycosides, viz., distolasterosides D1 and D 2 and pycno-podioside A; two previously known polyhydroxysteroids, viz., 5α-cholestane-3β,6α,8,15β,16β,26-hexaol and 5α-cholestan-3β,4β,6α,78,15β,16β,26-octol; and the known sodium 24,25-dihydro-marthasterone 3-sulfate were isolated from the Far-Eastern starfish Lethasterias fusca. The structures of these compounds were elucidated by NMR spectroscopy and mass spectrometry.
