摘　　要： 应用微波加热技术,对玫瑰茄籽进行干燥处理;以石油醚为溶剂,采用回流法提取玫瑰茄籽油。利用正交实验探讨微波处理温度、微波处理时间、提取时间、提取温度和料液比对玫瑰茄籽油提取得率的影响。结果表明,影响玫瑰茄籽油提取得率的因素主次顺序为:料液比>微波处理温度>提取温度>微波处理时间>提取时间;最佳提取工艺条件:料液比为1:9、微波处理温度为90℃、提取温度为50℃、微波处理时间为150s、提取时间为3h,得率为14.08%,提取率为85.5%。 Microwave assisted extraction method was used in drying treatment of roselle seed.Using reflux extraction with petroleum ether as solvent to extracted oils from roselle seed.The effect of microwave treatment temperature,microwave treatment time,ultrasonic temperature,extraction time,extraction temperature,solid-liquid ratio on the oil extraction efficiency were investigated by orthogonal experiments.The results showed that the primary and secondary order of the factors influencing oil extraction efficiency were as follows：solid-liquid ratio microwave treatment temperatureextraction temperaturemicrowave treatment timeextraction time.The maximum extraction efficiency of roselle seed oil could reach 14.08% and the extraction rate could reach 85.5% under the solid-liquid ratio of 1：9,microwave treatment temperature of 90℃,extraction temperature of 50℃,microwave treatment time of 150s and the extraction time was 3h.
