摘　　要：采用超声波技术对鼠曲草黄酮提取工艺进行研究,选择功率,提取温度,提取时间,料液比为因素进行正交实验,优选出超声提取最佳工艺,并与常规热回流提取法作了比较研究。结果表明:超声波法优于常规热回流提取法。超声法的最佳提取条件为:使用60%乙醇,在温度70℃、超声波功率为140W、料液比l2∶5条件下提取30min,效果最佳。A novel extraction process of flavonoids from Chapha liumaffine D. Don by ultrasonic wave was tested. The optimum extracting conditions of flavonoids were investigated by using orthogonal experimental design. In comparison with the ethanol refluxing extraction technology, the results show that the ultrasonic method was superior to the ethanol refluxing technology. It was found that 1：25 of 60%ethanol to the bud of Chapha liumaffine D. Don weigh ratio was used with ultrasonic treatment last for 30 min at the temperature of 70℃ and ultrasonic power 140W.
