綠島產 (Xenia sp.) (GN51)傘軟珊瑚之有機層萃取物經層析分離後得到12個化合物,分別為isoxeniolide-A (1), xeniolide-B (2), 4b -hydroxgermacra-1(10),5-diene (3), parahigginone (4), GN51-118 (5), GN51-119 (6), floride A (7), xenione (8), 13-epi-9-desacetyl-xenicin (9), xenitorin C (10), xenitorin A (11), xenitorin B (12)。其中GN51-118 (5)為新骨架的化合物, GN51-119 (6)為新化合物。

上述化合物經癌細胞毒殺活性測試後，xeniolide-B (2), xenione (8), 13-epi-9-desacetyl-xenicin (9)對P-388、HT-29細胞株均有顯著的抑制作用，化合物5對P-388細胞株有抑制作用。

Organisms of Formosan soft coral Xenia sp. (GN51) (collected at green island off Taiwan) were freeze-dried to give 600 g of a solid, which was extracted with CH2Cl2 and CH2Cl2/MeOH (1:1). After removal of solvent in vacuo, the residue was chromatographed over Sical gel 60 separation resulated in the isolation of two new diterpenes, GN51-118 (5) (new carbon skeleton) and GN51-119 (6), five known diterpenes isoxeniolide-A (1), xeniolide-B (2), floride A (7), xenione (8), 13-epi-9-desacetyl-xenicin (9) as well as five sesquiterpenes 4b- hydroxgermacra-1(10),5-diene (3), parahigginone (4), xenitorin C (10), xenitorin A (11)and xenitorin B (12)。
