摘　　要：通过单因素试验考察料液比、微波时间、微波温度、乙醇浓度对木脂素得率的影响,利用Box-Behnken Design响应面法优化提取工艺。结果表明:微波辅助提取樟叶木脂素的最佳条件为微波时间5min、料液比1∶26(g/mL)、乙醇浓度80%、微波温度60℃,在此条件下实际测得樟叶中木脂素得率为42.69mg/g,回归模型预测得率理论值达42.95 mg/g,实际值比理论值低0.61%,说明了该模型的有效性。An efficient microwave assisted extraction procedure for the lignans from the leaves of Cinnαmomum cαmphorα was investigated and optimized.Response surface methodology（RSM）based on a three-level four-factor Box Behnken Design（BBD）was employed to optimize the extraction conditions.The best extraction conditions were as follows：microwave time 5 min,ratio of material to ethanol 1：26（g/mL）,ethanol concentration 80%,microwave temperature 60 ℃.Under the optimization conditions,the experimental yield of lignans was 42.69%,which was well matched with the predictive yield of 42.95%.
