摘　　要：研究超声波辅助提取夏枯草总黄酮的最佳提取工艺条件。考察乙醇浓度、料液比、提取温度、超声功率及提取时间对夏枯草总黄酮提取率的影响,并在此基础上采用响应面分析法对提取工艺进行优化。以上因素对夏枯草总黄酮的提取率都有一定的影响,最佳提取工艺条件如下:乙醇浓度为60%;料液比为1∶12(g/mL);提取温度为61.4℃;超声功率为150 W;提取时间为40 min。在此条件下,夏枯草总黄酮的提取率可达到7.92%。Optimum extraction conditions of total flavonoids in Prunella vulgaris L.adopted ultrasound were studied.Effects of factors such as ethanol concentration,ration of solvent to sample,ultrasound power,extraction temperature and extraction time on extraction yield of total flavonoids in Prunella vulgaris L.had been investigated.On the basis of experimental results of single factor,experimental design of Box-Behnken was carried out and optimum extraction conditions were obtained.Extraction yield of total flavonoids in Prunella vulgaris L.reached 7.92 % under the following conditions： ethanol of 60 % condition,solvent to sample ratio 1∶12（g/mL）,extraction temperature 61.4 ℃,ultrasound power 150 W and extraction time 40 min.
