[Studies on the chemical constituents of marine sponge Iotrochota sp].
OBJECTIVE
To study the chemical constituents from the marine sponge Iotrochota sp.


METHODS
The compounds were isolated and purified by various column chromatography methods, and their structure wer identified cholesterol (1), nonadecyl ethers of glycerol (2), p-hydroxybenzaldehyde (3), (E)-4-(3,4-dihydroxyphenyl) but-3-en-2-one (4), 3,4-dihydroxybenzaldehyde (5), ethyl vanillin (6), hendecanoic acid (7), tricosane (8).


CONCLUSIONS
All compounds are isolated from marine sponge Iotrochota sp. for the first time.
