CHEMICAL CONSTITUENTS OF MARINE SPONGE GEL-LIODES SPINOSELLA IN THE SOUTH CHINA SEA / 中国海洋药物

Three known compounds have been isolated from the marine sponge Gel-liodes spinosella in the South China Sea. The crude ethanol extract was partitioned between ethyl acetate and water, and then between w-butanol and water. The butanol fraction was chromatographed on silica gel column to obtain thymidine(1l) ,phenylacetic acid(2)and L-(-)-3-phenylanine(3). Their structures were determined by UV,IR,1HNMR,and 13CNMR data.
