摘要
[目的]研究参薯叶黄酮的超声辅助提取工艺条件。[方法]以参薯叶为原料,选取提取温度、提取时间、超声波功率和料液比4个因素进行单因素试验,并在单因素试验基础上进行L9(34)正交试验,确定参薯叶黄酮的最佳超声提取工艺条件。[结果]优选的最佳提取工艺条件为:乙醇浓度60%,超声提取时间50 min,提取温度65℃,料液比为1∶30(g/ml);在此条件下,薯叶黄酮的提取率为5.17%。[结论]该方法优选出了薯叶黄酮的最佳超声提取工艺条件,为参薯叶资源的加工利用开辟新的途径。
[ Objective ] To study on the uhrasonic-assisted extraction technology of flavonoids from the leaves of Dioscorea alata L.. [ Methods ] Taking the leaves of D. alata as the raw materials, single factor test of extraction temperature, extraction time, ultrasonic power and solid-liquid ratio was conducted. Based on this, L9 （ 3^4 ） 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, 50 min extraction time, 65℃ extraction temperature, and 1：30 （g/ml）solid-liquid ratio. Under this condition, the extraction rate of 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.
