| titleOfInvention | Method for preparing polysaccharide selenite and application thereof |
| abstract | The invention belongs to a method for preparing polysaccharide selenite and an application thereof, which belong to the technical field of polysaccharide selenide. The invention is characterized in that the polysaccharide selenous acid ester is made essentially by a reaction of polysaccharide or a carbohydrate complex and a selenide reagent; the selenide reagent is selenium oxyhalide or the compound containing the selenium oxyhalide. A feeding molar ratio of the selenide reagent and hydroxyl groups in the polysaccharide is 1:0.1-20. The invention also comprises the applications of the polysaccharide selenous acid ester in preparation of anticancer drugs and ant-oxidation drugs. The polysaccharide selenous acid ester is produced by the reaction of the selenium reagent and the hydroxyl groups in sugar units, but not by selenite radicals substituting sulfate groups of the polysaccharide sulfate; the yield and the quality of the product are both higher than that of the products produced by other methods, and the selenium content is much higher than that of the products produced by the present technique. |
