摘　　要：以枸杞为原料,用乙醇作为提取剂,采用微波提取法对枸杞中总黄酮进行提取,以二次回归正交试验设计对结果进行优化分析。结果表明,乙醇浓度68.3%vol、微波时间100s、微波温度73℃、微波功率300W、液料比14.7∶1.0(mL∶g),在最佳条件下,总黄酮的提取率为19.52mg/g。The microwave-assisted extraction conditions of total flavonoids from Chinese Wolfberry were optimized with quadratic regression orthogonal experimental design. The results showed that the optimum conditions were as follows, concentration of ethanol 68.3%vol, microwave-assisted treating time 100s, temperature 73℃, microwave power 300W, ratio of liquid to material 14.7：1.0, and the extraction rate could reach 19.52mg/g under the optimum conditions.
