Title:
METHOD FOR PREPARING MIXTURE OF RARE GINSENOSIDES RH3 AND RK2 AND MIXTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/215265
Kind Code:
A1
Abstract:
A method for preparing a mixture of rare ginsenosides Rh3 and Rk2 and a mixture thereof. In the method, Rg3 is used as a raw material, β-glucosidase is used for enzymatic preparation, an acidification reaction is performed after an enzyme-catalyzed reaction is finished, and then solvent extraction is performed to separate a crude product of the mixture of Rh3 and Rk2. The proportion of Rk2 in the mixture is higher than that of Rh3.
