Abstract


Using various chromatography methods, four sesquiterpene phenols, dictyoceratin C (1), polyfibrospongol A (2), polyfibrospongol B (3), and 19-hydroxy-polyfibrospongol B (4) were isolated from the methanol extract of the Vietnamese marine sponge Smenospongia cerebriformis. Their structures were determined by 1D-, 2D-NMR spectra, HR-ESI-MS and in comparison with those reported in the literature.

Keywords. Smenospongia cerebriformis, sponge, sesquiterpene phenol.
