Chemical examination of a Taiwanese soft coral Lemnalia philippinensis led to the isolation of three oxygenated ylangene-derived sesquiterpenoids 1– 3, including two new metabolites, philippinlins A and B ( 1 and 2). The structures of these compounds were elucidated on the basis of detailed spectroscopic data. Compound 1 was shown to exhibit cytotoxicity against HepG2, MDA-MB231 and A549 cancer cell lines.
