綠島產紫羽珊瑚(Clavularia violacea Quoy and Gaimard)之有機層萃取物經細胞活性測試，發現對P-388、HT-29及A-549三種癌細胞有毒殺活性，以癌細胞毒殺活性為指標，將有機層之萃取物以矽膠管柱層析及HPLC進行分離純化，得到一種prostanoid (1)、兩種cembranoid diterpenes (2及3)、一種aromadedrane sesquiterpene (4)、一種neodollabellane diterpene (5)、(+)-curcuphenol (6) 及兩種sesquiterpene lactones (7及8)。其中1，2，4，7及8是新化合物。化合物1- 5具有很強的癌細胞毒殺活性。

The methylene chloride and acetone extracts of Formosan soft coral Clavularia violacea (Collected at Green Island) were found to exhibit significant cytotoxicity against P-388, A-549 and HT-29 cancer cell lines. Chromatographic separation let to the isolation of one prostanoid, 1, two cembranoid deterpenes, 2 and 3, one aromadedrane-type sesquiterpene, 4, one neodollabellane diterpene, 5, (+)-curcuphenol, 6 and two sesquiterpene lactones, 7 and 8. Compounds 1, 2, 4, and were new compounds. Compounds 1-5 exhibited significant cytotoxicity against P-388, HT-29 and A-549 cancer cell.
