摘要：

The sterol mixture of the southern Japan's soft coral, Sarcophyton glaucum, was found to contain 11 sterols including a novel sterol, 23,24ξ-dimethylcholesta-5,22-dien-3β-ol and a new diunsaturated C29 sterol. 22,23-Dihydrobrassicasterol and gorgosterol were the major components in free- and esterified sterols respectively. Brassicasterol was found in S.glaucum, in contrast to the ubiquity of 24-epibrassicasterol in the marine invertebrates in the northern districts. The new sterol (sarcosterol) was isolated; its structure as 23ξ,24ξ-dimethylcholesta-5,17(20)-trans-dien-3β-ol was based on spectral evidence and comparison with choiesta-5,17(20)-trans-dien-3β-ol. © 1979.
