Preparation method and application of Sargassum henslowianum fucosan sulfate

The invention provides Sargassum henslowianum fucosan sulfate which is composed of fucose and galactose and which has molecular weight of 4.0*10<5> to 6.0*10<5>. The Sargassum henslowianum fucosan sulfate is extracted from Sargassum henslowianum. By extracting Sargassum henslowianum crude polysaccharide and subjecting the crude polysaccharide to multiple times of purification with h ion exchange chromatography and molecular sieve chromatographic columns, the Sargassum henslowianum fucosan sulfate capable of being used for anti-herpes virus research is obtained. According to the scheme, the natural polysaccharide which has a novel antiviral action mode, is low in toxicity, efficient, safe and easy to accept can be separated from the marine medicinal resource Sargassum henslowianum, and a research basis can be provided for further developing antiviral drugs which have novel action mechanisms, definite curative effects and definite targets. The Sargassum henslowianum fucosan sulfate can play an antiviral role by effectively inhibiting herpes viruses from being adsorbed to the surface of host cells, and the acting site of the Sargassum henslowianum fucosan sulfate is the surface of thecells, can act on the first step of virus infection and does not enter the cells, so that the possibility of causing toxic and side effects is relatively small.
