微波辅助萃取当归油的实验研究

Microwave-Assisted Extraction of Volatile Oils from Angelica Sisnensis

用微波辅助萃取技术提取当归油,通过设计正交试验,得到了适宜的工艺条件:无水乙醇为提取溶剂,微波功率800w、微波辐射时间150s、液料质量比为4.71∶1,提取率约11.2%。

Microwave-assisted extraction of volatile oils from Angelica sisnensis was studied with the orthogonal experiment. The optimum condition of microwave extraction was obtained by the orthogonal experiment： the microwave power 800w, the radiating time 150s, the solvent-material mass ratio 4.71 ： 1, the optimum yield of microwave extraction was 11.2%.
