Steroid compounds from the Pacific starfish Lysastrosoma anthosticta

Two new steroid compounds, 3β,6α-dihydroxy-5α-cholesta-9(11),24-dien-23-one 3-sulfate and 3β,6α-dihydroxy-5α-cholest-9(11)-en-23-one 3-sulfate, were isolated from the Pacific starfish Lysastrosoma anthosticta as the corresponding sodium salts and identified. Two previously known glycosides of 24(S)-5α-cholestane-3β,6α,8,15β,24-pentol were also isolated and identified as sodium 24-O-β-d-glucopyranoside 6"-sulfate (pycnopodioside C) and sodium 24-O-β-d-xylopyranoside 4"-sulfate (luridoside A).
