Studies on the comporents and pharmacological action of polysaccharide from cordyceps sinensis

Polysaccharide of Cordyceps sinensis is the chief effctive component of the Cordyceps sinensis. After separation, purification and selection, a fungus which could engender the most polyssaccharide of Cordyceps sinensis dissolved in water was obtained.The components of the culture medium,a pilot production in the fermenting pot were improved, then the technology of purifying and refining was developed. Adopting the skills of chromatography and electrophoresis,the components and the structure of the polysaccharide of Cordyceps sinensis were analysed. The toxicological and pharmacological studies showed that the polysaccharide of Cordyceps sinensis was not toxiferous and possessed immunoenhancing and tumor-inhibiting effects significantly.
