A method for preparing a mixture of rare ginsenosides Rh3 and Rk2 and the mixture thereof, the method uses Rg3 as a raw material, carries out enzymatic preparation with β-glucosidase, and performs an acidification reaction after the end of the enzymatic catalysis reaction, and then separates and obtains by solvent extraction The crude product of a mixture of Rh3 and Rk2, in which the proportion of Rk2 is higher than that of Rh3. |
