A new polyhydroxysterol 1β,3β,5,6β-tetrahydroxy-5α-androstan-17-one (1) was isolated from the soft coral Sarcophyton glaucum.The structure of 1 was deduced from comparison of the spectral data with those of known 1β,3β,5α,6β-tetrahydroxysterols and confirmed by the synthesis starting from 1β,3β-dihydroxy-5,16-pregnadien-20-one (6a).
