Chemical Constituents and Cytotoxicity of Formosan Soft Corals Lemnalia Cervicorni and Dendronephthya spiniferaSung, Pei-Ying 10 July 2002 (has links)
Chromatographic separation of methylene chloride extracts of Formosan soft coral Lemnalia cervicorni May (collected at Green Island off Taiwan) led to the isolation of four ylangene sesquiterpenoids, GN40-29 (1), GN40-79 (3), GN40-169 (4), and GN40-173 (5). Acetylation of GN40-29 (1) gave a derivative GN40-29a (2). Compounds 3-5 were new compounds. Compound 1 showed cytotoxicity against HT-29 cell, while compound 5 was cytotoxic to P-388 cells.
The methylene chloride extracts of Formosan soft coral Dendronephthya spinifera Holm (collected at Green Island off Taiwan) were found to contain a new cadinene sesquiterpene, GN43-4 (6).
