Steroid compounds from ophiuroids II. Sulfated steroids from Ophiura sarsi and Ophiura leptoctenia

The previously described cholest-5-ene-3,4,21-triol 3-(sodium sulfate) has been obtained from extracts of the Far Eastern ophiuroidOphiura leptoctenia. Two new sulfated steroid polyols have been isolated from the ophiuroidO.sarsi; cholest-5-ene-3,4,21-triol 3,21-di(sodium sulfate) and cholest-5-ene-2,3,21-triol tri(sodium sulfate). The new polyol 4-acetoxycholest-5-ene-3,21-diol has been identified among the products of the desulfation of this ophiuroid.Pacific Ocean Institute of Bioorganic Chemistry, Far Eastern Branch, Academy of Sciences of the USSR, Vladivostok.
