[Study on the chemical constituents qf Spongilla Wagner].

OBJECTIVE: To study the chemical constituents in the fresh marine sponge Spongilla Wagner. METHODS: Compounds were separated and purified through various chromatographic methods and their structures were identified by spectroscopic data. RESULTS: Seven compounds were isolated and identified as 4-hydroxybenzoic acid (I), p-hydroxycinnamic acid (II), Pyrimidine-2, 4 (1H, 3H)-dione (III), Ferulic acid methyl ester (IV), Dodecyl ethers of glycerol (V), Tetracosane( VI). CONCLUSION: All compounds are isolated from this sponge for the first time.
