| Abstract: | The ultrasonic-assisted extraction processes of antioxidant polyphenols from Epimedii Folium was optimized by response surface methodology with the extraction rate of polyphenols and scavenging activity of DPPH as response value.The result showed that the optimal extraction conditions were ethanol concentration 57%, liquid-material ratio of 28 mL/g, extraction temperature 50℃, and extraction time 25 min for total polyphenols （34.58 mg/g） , ethanol concentration 58%, liquid-material ratio of 30 mL/g, extraction temperature 50 ℃, and extraction time 22 min for scavenging activity on DPPH free radical（88.4%）. |
