Abstract: The extracting conditions of sulfated polysaccharides (SPS) from the algae (sea weeds) were discussed in this paper.The two kinds of flow chart technics were contrasted and analyzed for the extracting by “hydrolyzation of enzyme” and the“extracting by poaching to different granularity algae such as 20、40、60、80 mesh respectively”. The maximum of SPSobtained was by granularity of 60 and poaching with the NO.2 flow chart.In this condition, the product yield was 3.10% andthe content of sulfate radical and polysaccharide was over 50%,which was higher than the result of literature.

Key words: sulfated polysaccharides, granularity, hydrolyzation of enzyme, condition of extracting
