| Abstract: | Ge-gen isoflavonid was extracted with 70% ethanol and hydrolyzed in HCl water solutions by the method of ultrasonic wave. Combing organic solvent extraction, the products of puerarin and daidzein were separated and purified. The results showed that the yield, purity of puerarin and daidzein were 1.2% , 97.8% and 0.5% , 98.2%, respectively. It was a time and energy saving, convenient and efficient way to extract and purify puerarin and daidzein from Pueraria lobata (Willd) Ohwi. |
