ABSTRACT
Objective To investigate the chemical constituents in the marine sponge, Spongia sp., collected from the Xisha Islands.Methods The pure chemical components from the petroleum ether extract of Spongia sp.were obtained by repeated column chromatography on silica gel,ODS,Sephadex LH-20 and semi-preparative HPLC.Their structures were determined by spectroscopic analysis and comparison with the reported data.The antifungal activity of those compounds was evaluated by dilution method.Results 9 compounds were isolated and identified,including smenodiol(1),smenospongorine(2),5-epi-smenospongorine(3),dictyoceratin C(4),epi-smenospongidine(5),dictyoceratin A(6),stigmasta-4,6,8(14),22-tetraen-3-one(7),3-oxo-4,6,8(14)-triunsaturated steroids(8),ergosta-4,6,8(14),22-tetraen-3-one(9).Conclusion Compounds 1~9 were isolated from the sponge of genus spongia for the first time.Compound 2、3、5 and 9 exhibited antifungal activities against Candida albicans,Trichophyton mentaqrophytes and Trichophyton rubrum with the MIC values of 12.5~25 μg/ml.
