摘　　要：目的:优选广玉兰种籽油的超声提取工艺。方法:以得油率为评价指标,以液固比、超声温度、超声时间为考察因素,采用响应面法优选超声提取工艺。结果:优选的提取工艺为液固比25∶1(ml/g),超声温度为40℃,超声时间为30 min。结论:所选工艺合理、可行,可用于广玉兰种籽油的提取;所建立的数学模型与试验观察数据相符。OBJECTIVE ： To optimize ultrasonic extraction process of Magnolia grandiflora seed oil. METHODS ： The ultrasonic extraction process was optimized by response surface methodology with the yield of oil as index using ratio of liquid to solid, ultrasonic temperature and ultrasonic time as factors. RESULTS： The optimal process were as follows： ratio of liquid to solid was 25 ： 1 （ml/g） ;ultrasonic temperature was 40℃ ; ultrasonic time was 30 min. CONCLUSIONS： The technology is reasonable, feasible and suitable for the extraction of M. grandiflora seed oil; observed responses are in close agreement with the predicted values of the mathematic models.
