| Abstract: | This paper reviews the extraction, component analysis and Biological activity on Polysaccharide in endocarp of Ginkgo biloba(GBEP). The polysaccharide is isolated from a hot-water extract of endocarp of Ginkgo biloba. GBEP is one of glycopeptides and composed of glucose,fructose,galactose and rhamnose. In vivo and vitro,GBEP can promote the immunological activity in normal and tumor-bearingmice. In vivo,GBEP can inhibit the growth of the solid tumor,S_180,and in vitro,it causes a decrease of the proliferation of S_180 cells in mice. GBEP may delay mice getting old as well. |
