本文在单因素试验基础上,采用响应曲面法优化了超声辅助提取鼠尾草挥发油的工艺参数。试验结果表明:超声辅助提取鼠尾草挥发油的最佳工艺参数为液料比10.4mL/g、提取温度51.6℃和超声时间18min,在此条件下得率达到最大值1.701%。
In this paper, based on the single factor experiment, the response surface method was used to optimize the ultrasonic-assisted extraction process parameters of sage volatile oil. The experimental results showed that the optimum extraction parameters of ultrasonic assisted extraction of sage volatile oil was 10.4mL / g, the extraction temperature was 51.6 ℃ and the ultrasonic time was 18min. Under the optimal conditions, the yield reached 1.701%.
