Marine sterols. XXI. Isolation of (24S)-3β-hydroxyergost-5-en-21-oic acid from a Sclerophytum sp. of soft coral

The lipid extract of the Sclerophytum sp. of soft coral, collected off the coast of the Andaman and Nicobar Islands, afforded a new sterol 1a. The structure of 1a was shown to be (24S)-3β-hydroxyergost-5-en-21-oic acid, the first member of a class of mari
