Abstract:

Plant polysaccharide involved in various physiological metabolism of the body, had broad phacology effect, such as regulation of immune, anti-tumor, resisting guard against a seni1ity, antivirus, hypoglycemic, antioxidation and so on. At present, the studies on increasing the production of polysaccharide and exploring the mechanism of its pharmaceutical activities were very popular. The article summarized the progress in structure, extraction method, pharmacological action, as well as in medicine, food, agricultural and other areas of application in the past years and provides reference for the utilization of plant polysaccharide.
