摘　　要：为了优化微波辅助提取葛根黄酮的工艺,通过单因素试验和正交试验研究微波辅助提取葛根黄酮的最佳工艺条件。结果表明,微波辅助提取葛根黄酮的最佳工艺条件为液料比35∶1(V/m,mL:g),提取时间13 min,微波温度75℃,乙醇体积分数50%,此条件下葛根黄酮的提取率最高,为7.31%。Total flavonoids were extracted from Radix puerariae by microwave-assisted method. And the extraction process was optimized by single factor tests and orthogonal design. The results showed that the optimum extracting conditions were, solu-tion to raw material ratio, 35：1 （V/m,mL：g）; microwave-assisted extraction time, 13 rain; extraction temperature, 75 ℃; ethanol volume fraction, 50%. The yield of total flavonoids under these conditions was 7.31%.
