摘　　要：为了从薏苡仁中提取薏苡仁油,分别考察提取方法、有机溶剂、乙醇浓度、微波时间、料液比、薏苡仁粉粒径对薏苡仁油提取率的影响。通过单因素和正交试验,确定采用微波法提取薏苡仁油的最佳工艺为以无水乙醇作为提取剂,微波时间10min,料液比1∶12(m∶m),薏苡仁粉粒径100目。该条件下薏苡仁油提取率为7.58%,薏苡仁油提取效率达84.7%。The influencing factors in the extracting adlay seed oil were studied. The factors include extraction method, organic solvent, ethanol concentration, microwave time, solid-liquid ratio and adlay seed powder size. The results of single factor test and orthogonal test showed that the optimum organic solvent was anhydrous ethanol, the optimum microwave time was 10 min, the optimum solid-liquid ratio was 1 ： 12（m ： m）, the optimum adlay seed powder size was 100mesh, and the adlay seed oil extraction rate was 7.58%, and the extraction efficiency was 84.7%.
