摘　　要：目的通过正交试验法优化艾叶挥发油提取工艺。方法采用正交试验法考察工艺,其中考察因素为提取时间(A)、料液比(B)和浸泡时间(C),每个因素取3个水平,以得油率为考察指标对艾叶挥发油的提取工艺进行优选。结果艾叶挥发油最佳提取条件为料液比1∶10、浸泡4 h、提取3 h,平均得油率为0.416%,RSD=2.64%(n=3)。结论优选的提取工艺得油率较高,工艺稳定可行,可为实际生产提供依据。Objective To optimize the best extracting process of essential oil of Folium A rtemisiae argyi. Methods The orthogonal test was applied. The following factors with three levels were considered：extracting time （A）, the proportion of material to solvent （B）, and soaking time （C）. Extracting yield was investigated as the evaluation indicators. Results The best extracting process was obtained at the following conditions：ratio of solid to liquid of 1：10, soaking time of 4 h, extraction time of 3 h. The average oil production rate was 0.416%, RSD=2.64%（n = 3）. Conclusion The preferred process has higher oil yield, it is stable, feasible, and can provide basis for actual production.
