摘要
目的:优选款冬花中绿原酸的最佳超声提取工艺。方法:以绿原酸为指标,采用单因素考察和正交试验结合的方法,对乙醇浓度、乙醇倍量、提取时间3个因素进行考察,优选提取工艺。结果:乙醇浓度对款冬花中绿原酸的提取率影响最大,其次是提取时间,乙醇倍量影响最小。结论:超声提取款冬花中绿原酸的最佳提取工艺参数为70%乙醇,乙醇倍量为30,提取时间为30 min。
Objective：To optimize ultrasonic wave extraction technology of the chlorogenic acid from Tussilago farfara L.Methods：In the method of one -way and orthogonal test,the ethanol concentration,solid -liquid ration and extraction time were studied with the chlorogenic acid from Tussilago farfara L.as the target of the test.Results：The concentration of alcohol is the major factor followed by extraction time and solid-liquid ration.Conclusion：The parameters of the best ultrasonic wave extraction technology of the chlorogenic acid from Tussilago farfara L.are as follows：70%ethanol,solid liquid ration 1：30,extracting 30 min.
