摘　　要：以黄酮提取率为考察指标,采用单因素试验和正交试验,进行了微波辅助乙醇提取凤尾蕨(Pteris multifide Poir)中总黄酮的研究,得到微波辅助提取凤尾蕨中总黄酮的最佳工艺条件为乙醇体积分数60%,料液比1∶60(g∶m L),微波功率320 W,微波提取时间60 s。此工艺条件下,凤尾蕨中总黄酮的提取率为3.318%。To improve extraction rate of flavonoids,the single factor experiments and orthogonal experiments of microwave assisted extraction of total flavonoids from Pteris multifide Poir were conducted using ethanol as solvent.The optimal conditions were the concentration of ethanol of 60％,the material-liquid ratio of 1∶60（g∶mL）,the microwave power of 320 W,the extraction time of 60s.Under the optimal conditions,the extraction rate of total flavonoids from Pteris multifide Poir was 3.318％.
