Seven new phragmalins with a C-30 carbonyl moiety, named moluccensins A−G (1−7), among which moluccensins A−F, possessing a Δ8,14 double bond, and moluccensin G (7), containing conjugated Δ8,9 and Δ14,15 double bonds, were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis. The structures of these compounds were established on the basis of single-crystal X-ray diffraction analysis and spectroscopic data. This is the first report of phragmalins with a conjugated C-30 carbonyl group.
