摘要：

In addition to the known (20S,22E)-cholesta-1,4,22-triene-16-beta,18,20-triol-3-one, (20S,22E)-24-methylcholesta-1,4,22-triene-16-beta,18,20-triol-3-one, and (20S,22E)-24-methylcholesta-4,22-diene-16-beta,18,20-triol-3-one, the methanol extract of the Mediterranean anthozoan Antipathes subpinnata was shown to contain five new sterols: (20S,22E)-cholesta-1,4,22-triene-18,20-diol-3-one, (20S,22E)-24-methylcholesta-1,4,22-triene-18,20-diol-3-one, (20S)-cholest-4-ene-16-beta,18,20-triol-3-one, (20S,22E)-cholesta-4,22-diene-16-beta,18,20-triol-3-one, and (20S,22E)-24-methylcholesta-4,22-diene-16-beta,18,20-triol-3-one, whose stereostructures were elucidated on the basis of physicochemical evidence. The previously unassigned chirality at C-20 of the known sterols has been also established as S.
