| Abstract: | Ultrasound-assisted extraction of flavonoids Aspongopus chinensis Dallas optimal process was studied.Ethanol as solvent,ultrasonic extraction as auxiliary equipment,single factor test to determine the impact of flavonoids extracted from the scope of the main factors and their optimal level by L9(34) orthogonal test to determine the optimal extraction conditions. Factor affecting the ultrasonic-assisted extraction Aspongopus chinensis Dallas flavonoids from primary to secondary is the solid-liquid ratio,extraction time,ethanol concentration and extraction temperature.Optimum conditions are solid-liquid ratio 1:30,extraction time 30 min,70% ethanol concentration,extraction temperature of 60℃.The content of flavonoids reached the maximum of 17.1 mg·g—1 at the optimum conditions. |
