摘　　要：研究了微波辅助水蒸气法提取金刺梨挥发油工艺。通过单因素试验研究萃取溶剂、微波处理时间、微波火力、Na Cl添加量对挥发油提取率的影响,再通过正交试验进一步优化提取条件,得出影响金刺梨挥发油提取率的因素的主次顺序为Na Cl添加量>微波处理时间>微波火力,最终确定了微波辅助水蒸气法提取金刺梨挥发油的最佳工艺为Na Cl添加量3%、微波处理时间4 min、微波火力为中火,在此最佳条件下,金刺梨挥发油的提取率为1.75%。The extraction processing technology of volatile oil from Rosa sterilis by microwave–assisted steam was studied. The effect of extraction agent,microwave processing time,microwave processing power,additive amount of Na Cl on extraction rate were studied by single factor experiment. Further optimization was conducted by orthogonal experiment. And the result showed that the factors influencing volatile oil from rosa sterilis yield in order were Na Cl addition〉microwave processing time〉microwave processing power. The optimal conditions were Na Cl addition of 3%,microwave processing time of 4 min and middie microwave processing power. The extraction yield of volatile oil from Rosa sterilis was 1.75%.
