摘　　要：为了探索超声波辅助提取急弯棘豆黄酮的最佳工艺条件,试验以急弯棘豆黄酮的含量为考察指标,通过单因素和正交实验设计试验研究提取超声功率、温度、时间、乙醇浓度、料液比对急弯棘豆黄酮提取率的影响,筛选出最佳提取工艺。结果表明,影响急弯棘豆超声辅助提取的主要因素依次为超声功率、温度、超声时间和料液比。超声波辅助提取弯棘豆黄酮最佳提取工艺条件:乙醇浓度在60%,超声时间为45min,超声波功率为800 W,温度45℃,料液比为1∶10。最高提取率为1.97%。To investigate the optimum extraction of flavonaids from the Oxytropis deflexa by ultrasonic wave,according to the content of total flavonoids,single factor and orthogonal experimental designs were employed to select the best extracting ultrasonic power,temperature,time,ethanol concentration and ratio of material.The results showed the optimum conditions of ultrasonic extraction were that ethanol concentration of 60％,extracting at 45 min,solid to liquid ratio of 1∶10 （g/mL） and ultrasonic power of 800 W.Under those conditions,the total flavonoids extraction yield from the Oxytropis deflexa was 1.97％.
