Hydrolytic method of Chinese potato saponin

The invention relates to a hydrolysis method of dioscin. A solid acid catalyst is added to the reaction solution containing the dioscin according to the proportion of 0.1g to 100g / 100ml of extract and then the reaction solution is placed in water bath of 50 DEG C to 90 DEG C for reaction for 2h to 16h; after the hydrolysis, the reactant obtained is cooled to the room temperature and filtered in vacuum and the filter residue is dried at the temperature of 20 DEG C to 80 DEG C; the filter residue is extracted in organic solution for 4h to 12h continuously, the extract is separated and the organic solution thereof is recycled; finally the dioscin solid is obtained. The solid acid catalyst system adopted by the invention is a multiphase reaction; hydrogen ions are restrained on the surface of the catalyst rather than going into the body of the reaction solution, therefore, the acidification of the reaction solution is avoided and the loss of the hydrogen ions is rather small. The experimental result shows that the pH value of the solution phase after hydrolysis is 4 to 5 and the concentration of the hydrogen ions in the solution is 10,000 times lower than that of the solution which is hydrolyzed by hydrochloric acid, thus greatly reducing the pollution to the environment. The hydrolysis method has simple technology, moderate hydrolysis conditions and high hydrolysis conversion rate of the dioscin which is as high as 98 percent, thus fundamentally solving the problems of serious environmental pollution and equipment corrosion occurring in the inorganic acid catalysis hydrolysis process.
