    Abstract：Marine polysaccharides are akind natural polysaccharides which have many unique bioactivities, such as immunity regulation, antitumor, lowering blood lipid，lowering blood sugar, radioprotection，antimutation, antioxidation and antihypoxia. This article introduces the methods of producing marine polysaccharide from many low-valued marine organisms and the present condition and prospect of this high-valued marine polysaccharides.

    Key words：laminarin; chitosan; spirulina polysaccharide; high-valued
