| Abstract: | The polysaccharide DEI, DEII were isolated from Sargassum pallidium through water extraction, ethanol precipitation, DEAE-Septkadex A-25 column chromatography.The content of total sugar were 52.4%. Chemical composition analyzed by TLC and GC-MS showed that they were composed of xylose, fucoidan, galactose,fructose, mannose and the glucose. And the fucoidan was the primary component.The polysaccharides DEI,DEII were found to have inhibition activities on P388 tumor cell hnes in vitro. |
