Abstract
A new cembrane-type diterpene, 11,12-epoxy-sarcophytoxide (1), along with five related diterpenoids (2, and 4–7), has been isolated from the soft coral Lobophytum sp. The structure of the new compound 1 was elucidated on the basis of detailed analysis of its spectroscopic data, and by comparing its NMR spectral data with those of the model compounds.
