Abstract
Three indole compounds(namely 1H-Indole-3-carboxaldehyde(1),1H-Indole-3-carboxylic acid(2),and ethyl 1H-Indole-3-carboxylate(3)) and 3-β-5-en-cholest(4) were isolated from the south China sea sponge,Xetospongia testudinaria,by repeatedly silica gel and Sephedex LH-20 chromatography.Their structures were identified by extensive spectroscopic analysis together with NMR、IR and EI(ESI)-MS spectrum,and further determined by comparing their physical and chemical data with the literature.All the identified compounds are isolated from the sponge,Xetospongia testudinaria,at the first time.
