The lipid extract of the soft coral, Sarcophyton glaucum, was found to contain significant amounts of cembrane-type diterpenes. The structures of four major components, sarcophytol-A, sarcophytol-A acetate, sarcophytol-B, and sarcophytonin-A were characterized on the basis of spectral data and degradative studies by ozonolysis. Sarcophine and 16-deoxosarcophine, which were reported to be abundant in S. glaucum collected in the Red Sea, were not found yet.
