| 摘 要： | 采用液膜法提取杜仲叶中绿原酸,通过正交实验对液膜制备工艺和绿原酸提取工艺进行了研究。结果表明,液膜制备的最佳工艺条件为:NaOH浓度4mol.L-1、吐温-20质量分数8%、搅拌速度350r.min-1;绿原酸提取的最佳工艺条件为:混合时间8min、乳水比1∶2、搅拌速度100r.min-1、油内比3∶1。液膜法实现了对绿原酸的提取和浓缩,为进一步开发利用绿原酸提供了依据。

| Abstract: | Chlorogenic acid was extracted from Eucommia leaves by liquid membrane method.The preparation conditions of liquid membrane and the extraction conditions of chlorogenic acid were optimized by orthogonal experiment.The results showed that the optimum preparation conditions of liquid membrane were as follows:NaOH concentration of 4 mol·L-1,Tween-20 mass fraction of 8%,stirring speed of 350 r·min-1,the optimum extraction conditions of chlorogenic acid were as follows:the mixing time of 8 min,the emulsion/external-phase ratio of 1∶2,stirring speed of 100 r·min-1,the oil/internal-phase ratio of 3∶1.By liquid membrane method,the chlorogenic acid was extracted and concentrated successfully,and provided a basis for exploiting chlorogenic acid. |
