| titleOfInvention | Method for hydrolyzing baicalin in baicalin to yellow baicale |
| abstract | The invention discloses a method for improving the hydrolysis rate of baicalin in Astragalus membranaceus, and belongs to the technical field of natural product extraction and separation. The method comprises the following steps: 1) determining the enzymatic hydrolysis rate of the self-contained xanthine in the medicinal material of the astragalus: the scutellaria sinensis (known as the content of baicalin), pulverizing into a coarse powder, taking 50.0 g, adding baicalin 10.0 g, adding water 200mL, adjust the pH to 4.5, heat at 50 ° C for 3 hours, suction filtration, dregs drying, determine the content of baicalin, calculate the enzymatic hydrolysis rate. 2) According to the enzymatic hydrolysis rate of the xanthine enzyme to be treated, the amount of glycosidase and auxiliary enzyme is selected; 3) the scutellaria sinensis is pulverized, and the water of the medicinal material is added 3 to 5 times of the water to infiltrate, and the pH value of the mixed system is adjusted. To 4-6, the glycosidase and the auxiliary enzyme are added, and the mixture is incubated at 40 to 60 ° C for 10 to 14 hours to complete the hydrolysis. The hydrolysis rate of baicalin in the medicinal material is greater than 95%. |
