Article abstract of DOI:10.1007/BF00598760

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-cholestane<*>3β,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).
