目的：本研究采用响应面优化超声波提取栀子中油脂的提取工艺。方法：通过单因素实验，确定提取时间、液料比和提取次数为影响因子，采用响应面法分析3个因素对栀子油脂提取率的影响。结果：最佳提取条件为提取时间为28.7min，液料比为11.62：1，提取次数为3.36次，在此条件下，做3次平行试验进行验证，得到栀子油脂的提取率为13.50%，与模型预测值之间拟合性较好。结论：超声波提取有效的提高栀子油脂的提取率，为栀子油脂的开发利用提供了一定的依据。

This study aimed to optimize the ultrasonic extraction of gardenia oils from Gardenia jasminoides Ellis.by response surface analysis methodology(RSM).The duration of extraction, ratio of liquid to materials and extracting times were selected as impact factors based on single-factor experiment.RSM was adopted to learn the effects of the three factors on the extraction rate of Gardenia oil from Gardenia jasminoides Ellis.As a result,it was found that the duration of extraction was 28.7min,while the ratio of liquid to materials was 11.62：1,and the number of extracting times were 3.36.Under this extracting condition,the average extraction rate of the oil was 13.5% according to three validation experiments,fitting the predicted value well.In conclusion,it was demonstrated that the ultrasonic extraction method effectively improved the extraction rate of gardenia oil,providing a certain basis for the development and utilization of gar denia oil.
