摘　　要：为优化得到车前草中总酚的最佳微波提取工艺条件,通过单因素和正交试验进行筛选。结果表明:影响车前草总酚提取率的主要因素顺序为,微波处理时间>乙醇浓度>料液比>微波功率;车前草总酚的最佳提取工艺为,60%乙醇、料液比1∶15(g∶mL)、微波处理3 min、微波功率为450 W。在此条件下车前草总酚的提取率最高,为3.61%。该法对车前草总酚提取率高,且缩短提取时间,节约能源。To explore factors affecting the extraction rate of total phenols from Plantago asiatica L. , the optimal extraction conditions using microwave-assisted extraction were optimized by single factor and orthogonal experiment. The results showed that the order of different effect factors on yield was microwave-heating time 〉 ethanol concentra- tion 〉 solid-liquid ratio 〉 microwave power. The optimal conditions were as follows： 60% ethanol, 1：15 （g： mL） ratio of solid-liquid, extracting 3 min, microwave power 450 W. The yield of total phenols was up to 3.61% under these conditions. The method had the advantages of higher yield, less extraction time and energy.
