摘　　要：从新疆一枝蒿中提取总黄酮并对其提取工艺进行优化。采用超声波法提取新疆一枝蒿总黄酮,通过响应面法分析,得到提取新疆一枝蒿总黄酮的最佳工艺条件:乙醇体积分数76%,料液比1:11(g/mL),超声时间32min。在最佳工艺条件下,新疆一枝蒿总黄酮得率为4.50%,比优化前提高了34%。In order to develop an optimal process for the ultrasonic-assisted extraction of flavonoids from Artemisia rupestris L., some crucial process conditions, namely ethanol concentration, material/liquid ratio and length of ultrasonic treatment were optimized using response surface methodology. Ethanol concentration of 76%, material/liquid ratio of 1：1 and length of ultrasonic treatment of 32 min were found optimum. Under the optimized conditions, the yield of flavonoids was 4.50%, with a 34% increase than before optimization.
