説明
The southern Japan's soft coral, Sarcophyton glaucum, was found to contain several polyhydroxylates steroids. One of the minor components was isolated and its structure was established as 24 xi-methylcholestane-1 beta, 3 beta, 5 alpha, 6 beta, 25-pentol 25-monoacetate from spectral evidence and from comparison with a reference compound, 5 alpha-spirostan-1 beta, 3 beta, 5 alpha, 6 beta-tetrol, which was synthesized from ruscogenin. A mixture of 1 beta, 3 beta, 5 alpha, 6 beta-tetra hydroxy C27- and C28-sterols was also isolated.
