微波辅助提取草果挥发油工艺研究

摘要

目的:优化微波辅助提取元阳草果挥发油工艺.方法:采用单因素实验、多因素正交实验,考察挥发油得率.结果:微波功率对挥发油产率影响最为显著,最佳提取条件为:液料比15:1、处理时间5min、微波功率800W.结论:采用最佳实验条件提取草果挥发油,产率可达2.82%.%Objective:To study the effect factors of microwave-assisted extraction of essential oil from Amomum tsao -ko collected in Yuanyang. Methods :With single factor and orthogonal experiments. Results :The optimal condition:the ratio of water and stuff 15∶1 (mL/g), microwave irradiation time 5min and microwave power 800W. Conclusion:Under the optimized condition,the highest extraction rate of essential oil was 2.82％.
