Abstract
Polysaccharide is an important class of biological macromolecules. It has a variety of biological activity, such as antitumor, an-tivirus, anti-oxidation, immune activity regulation. The biological activity of polysaccharide has a direct relationship with its struc-ture. Thus the structural modification of polysaccharide by an appropriate method can increase its biological activity and decrease some side effects, which including the chemical, physical and biological methods. The chemical modification method, structural analysis, identifi-cation technique and their research progress of polysaccharide modification are outlined so as to provide the basis for the further study on the polysaccharide drugs.关键词
