Research Progress on Tea Polysaccharide

Tea polysaccharide is a kind of water-soluble compound polysaccharide, which relatively molecular weight is 1×104-5×104. Main compositions of tea polysaccharide include glucose, arabinose, ribose, galactose, mannose, xylose and fructose. Modem medical science shows tea polysaccharide possesses important physiological functions to human body. The chemical compositions and qualities, structure analysis, extraction and physiological functions of Tea polysaccharide were summarized in this article. The developing prospect of Tea polysaccharide has also been looked forward in the paper.
