| titleOfInvention | Method for purifying ginsenoside Rh2 |
| abstract | A method for purifying ginsenoside Rh2 is used for purifying an enzyme reaction liquid for preparing Rh2 by catalyzing Rg3 with beta-glucosidase, and aims to solve the technical problems of complex operation, time and labor consumption and high cost of the existing purification method. The purification method comprises the following steps: extracting the enzyme reaction liquid by using an extraction system, standing for layering, taking an upper solution, and recovering a solvent from the upper solution to obtain an Rh2 product; the extraction system consists of ammonium sulfate, ethanol and ethyl acetate, the dosage of the ammonium sulfate is 2-20g/100ml of enzyme reaction liquid, the total volume of the ethanol and the ethyl acetate is 0.5-5 times of the volume of the enzyme reaction liquid, and the volume ratio of the ethanol to the ethyl acetate is 1: 1-4. |
