阔叶十大功劳叶挥发油提取工艺研究

Optimization of Ultrasonic Extraction of Volatile Oil from Mahonia Bealei Carr

为获取阔叶十大功劳叶挥发油提取的最佳工艺,采用响应面法优化超声提取法,以阔叶十大功劳叶挥发油得率为研究指标,在单因素试验的基础上,采用响应面法设计试验,分析研究阔叶十大功劳叶挥发油最佳提取工艺条件。结果表明,最佳提取条件为:超声温度50℃;超声时间40 min;料液比1∶20;阔叶十大功劳叶挥发油提取率为2.45%,与理论预测值2.44%的相对误差为0.04%。验证试验结果证明此提取工艺稳定合理,准确可靠,是提取阔叶十大功劳叶挥发油的可行方法。

In order to get the best technology of volatile oil extraction from Mahonia Bealei Carr,it used the ultrasonic extraction with response surface methodology in the paper. Taking volatile oil yield as the index, with the single factor experiments and the response surface optimization method, it got the optimiza- tion. The research results showed that the optimal process conditions：ultrasonic temperature 50 ~C ;ultra- sonic time 40 min;material liquid 1： 20,with these conditions it got the volatile oil yield as 2.45%, the theoretical prediction is 2.44% ,and the error rate is 0. 04%. The experimental results showed that this method is stable and easy to control.
