【摘要】 [Objective] To study the ultrasonic-assisted extraction technology of total flavonoids from the leaves of Dioscorea alata Linn.[Method] With the leaves of D.alata as the raw materials,single factor test on the extraction temperature,extraction time,ethanol concentration and solid-liquid ratio was conducted.Based on this,L9(34) orthogonal test was conducted in order to determine the optimal ultrasonic-assisted extraction technology for the flavonoids from D.alata leaves.[Results] The optimal extraction technology was as follows:60% ethanol concentration,50 min extraction time,65 ℃ extraction temperature,and 1:30(g/ml)solid-liquid ratio.Under this condition,the extraction rate of total flavonoids from D.alata leaves was 5.17%.[Conclusion] The optimal ultrasonic-assisted extraction technology of flavonoids from D.alata leaves was selected,which provided new approach for the processing and utilization of D.alata leaves.
