| 摘 要： | 在单因素试验的基础上,采用Box-Behnken设计对杜衡挥发油超声波协同微波提取工艺中的液料比、微波功率和微波时间3因素的最优化组合进行了定量研究,建立并分析了各因素与得率关系的数学模型.结果表明:最佳的工艺条件为液料比10mL/g,微波功率234W和提取时间131s.经试验验证,在此条件下得率为8.29%,与理论计算值8.32%基本一致.说明回归模型能较好地预测杜衡挥发油的提取得率.并采用气相色谱-质谱联用技术对杜衡挥发油成分进行了分离鉴定,分离出30种成分,确认了其中21种,采用峰面积归一化法确定了各成分的相对含量.

| Abstract: | The influences of solvent to material ratio,microwave power and extraction time on the extraction yield of volatile oil from Asarum forbesii Maxim with the ultrasonic-microwave synergistic extraction(UMSE)technique were studied.Box-Behnken experimental design was based on the single factor experiments.One mathematical model established and analyzed by response surface methodology(RSM)was adequate to describe the relationships between the studied factors and the response of volatile oil extraction yield.Base... |
