摘　　要：本文以灯笼草为原料,研究超声波提取灯笼草总黄酮的最佳工艺。通过单因素试验研究乙醇体积分数、料液比、超声波功率及超声时间对总黄酮提取量的影响。以此为基础,采用正交试验设计,优化超声波提取灯笼草总黄酮工艺条件结果为乙醇浓度为60%,最佳料液比为1︰40,提取温度为50℃,超声波功率为100 W,提取时间30 min为最佳提取条件。黄酮提取率为5.66%。This paper studies the best technique of ultrasonic extraction of the flavonoids by using lantern grass as raw material. The effects of ethanol volume fi＇action, liquid ratio, ultrasonic power and ultrasonic time on total flavonoids were studied through a single factor experiment. On this basis, using the orthogonal experiment design, optimize the ultrasonic extraction flavonoids lanterns grass process conditions the results for the ethanol concentration was 60 %, the best ratio of material liquid 1 ： 40, extraction temperature is 50 ℃, the ultrasonic power is 100 W, extracting time 30 rain as the best extraction conditions. The extraction rate of flavonoids is 5.66 %.
