基于响应面法的鸡矢藤挥发油提取工艺优化研究

Study on Optimization of Extraction Process of Volatile Oil from Paederia scandens Based on Response Surface Method

以鸡矢藤为原料,在单因素试验基础上,使用Box-Benhnken响应面法,将鸡矢藤挥发油含量作为响应值,建立数学回归模型,分析优化提取鸡矢藤挥发油工艺。结果表明,鸡矢藤挥发油最佳提取工艺参数是粒径429μm、料液比1∶9.3(g∶mL)、提取时间2.63 h,在该条件下,挥发油含量为3.12%,鸡矢藤挥发油提取稳定、可靠。

Paederia scandens was used as the raw material,on the basis of single-factor experiment,the Box-Benhnken response surface method was used to establish a mathematical regression model using the volatile oil content of Paederia scandens as the response value,and to analyze and optimize the extraction process of Paederia scandens volatile oil.The results showed that the optimal extraction process parameter for volatile oil from Paederia scandens was particle size 429μm,solid-liquid ratio 1∶9.3(g∶mL),extraction time 2.63 hours,under this condition,the volatile oil content was 3.12%.The extraction of volatile oil from Paederia scandens was stable and reliable.
