| Abstract: | Objective] The aim was to provide an optimum method to extract flavonoids from Sophora japonica L..Method] The ultra-high hydrostatic pressure extraction(UPE) technology was applied to extract the total flavonoids from Sophora japonica L.,and it was compared with other three methods of ultrasonic extraction,thermal circumfluence and decoction extraction.Result] The yields of flavonoids extracted UPE,thermal circumfluence,decoction and ultrasonic extraction were 11.30%,10.69%,8.54% and 10.12% respectively.The DPPH radical scavenging rates of the four extraction methods were 81.73%,76.87%,70.50% and 81.41% respectively.Conclusion] Compared with thermal circumfluence,decoction and ultrasonic extraction,UPE had high yield,short extraction time and high antioxidant activity,which had broad application prospect in the extraction of Chinese herbal medicine. |
