ABSTRACT
Chinese medicine polysaccharide is an important active biological macromolecule, which has a broad application prospect. However, there are still many deficiencies in the quality evaluation and control of polysaccharides. Based on the existing problems in the quality control of traditional Chinese medicine polysaccharides, current review analyzes the methods of extraction, separation and purification, characteristic identification, content determination and structure analysis of Chinese medicine polysaccharides, and draws the following

conclusions:

①Based on the clinical application of Chinese medicine, decoction is recommended as the extraction method in the basic study of effective substances of Chinese medicine polysaccharides; ②On the basis of impurity removal, HPGPC can achieve the separation, purification and content determination of Chinese medicine polysaccharides at the same time, supplemented by MS or NMR can achieve the quantitative and qualitative analysis of Chinese medicine polysaccharides; ③Based on the characteristic identification, select the suitable pure polysaccharide, dextran or monosaccharide reference; ④HPSEC-MALLS-RID is specific, accurate, and beneficial to the study of structure-activity mechanism of polysaccharides. The review suggested that the comprehensive evaluation and control of the quality of Chinese medicine polysaccharides should be based on extraction, separation and purification, on the premise of characteristic identification, on the basis of content determination, supplemented by structural analysis, which is to provide useful reference for the quality research of Chinese medicine polysaccharides.
