中文摘要: 以干燥的薏米为原料，采用正交试验研究薏米油的提取工艺条件。结果表明：薏米油产率的影响因素依次为：溶剂（D）＞温度（A）＞时间（C）＞料液比（B）；最佳提取条件为A1B1C2D2，即提取溶剂为正己烷，为温度30℃，时间20 min，料液比为1∶8（g/mL），此时薏米油的提取率达到最优，为12.05%。薏米油的抑菌试验表明：薏米油对大肠杆菌的有效抑菌浓度为20%，对金黄色葡萄球菌的有效抑菌浓度为40%，对普通变形杆菌几乎无抑制效果。
Abstract:In this experiment，the extraction conditions of adlay seed oil by orthogonal test method and the evaluation of bacteriostasis effect were studied.The results showed that the impact of the adlay seed oil yield factors were followed by solvent（D）＞temperature（A）＞extraction time（C）＞raw and liquid ratio（B）.The best conditions for extraction of adlay seed oil was A1B1C2D2，in other words，solvent was n-hexane，temperature was 30℃，raw and liquid ratio was 1∶8（g/mL），extraction time was 20 min.The adlay seed oil extraction rate had reached 12.05%in the best condition.The results of inhibition effect of adlay seed oil showed that the minimum inhibitory concentration to Escherichia coli was 20%，Staphylococcus aureus was 40%，and it had no inhibitory effect to proteus vulgaris.
