Metagenomics and their application in the research of marine natural drugs / 中国海洋药物

ABSTRACT

Objective To study the chemical constituents of marine sponge Craniella australiensis collected from the South China Sea.Methods Compounds were isolated and purified by column chromatography and their structures were identified based on spectral analyses and chemical evidence.Results Four compounds were isolated from the ethanol extract and identified as ?-sitosterol(Ⅰ),3?,6?-stigmast-4-en-3,6-diol(Ⅱ),1,12-diazacyclodocosane-2,11-dione(Ⅲ),uracil(Ⅳ).Conclusion All these compounds were isolated from this sponge for the first time.
