Formosan soft coral Xenia sp. (GN47) (collected at east coast of Taiwan) was extracted with methylene chloride and acetone. Chromatographic separation of the organic extract resulted in the isolation of six diterpenoids, 13-epi-9-desacetylxenicine (1), xenicinone (2), 13-epi-7,8-epoxide-9-des-
acetylxenicine (3), isoxeniolide-A (4), 7,8-epoxide-4,12Z-iso-xeniolide-A (5), 4,12Z-9-deoxy-isoxeniolide-A(6) as well as two cadinane sesquiterpenes, xenitorins B (7) and xenitorins A (8).
Compound 6 is a new compound. We revised structure of compound 2 and determined the stereochemistry of compound 3.
