摘要
以中华苦荬菜为试材,总黄酮提取率为评价指标,采用微波辅助提取,单因素和正交实验的方法研究了料液比、乙醇浓度、提取时间和提取温度对中华苦荬菜总黄酮提取率的影响。结果表明:在所考察的因素中,对中华苦荬菜中总黄酮提取率影响的主次顺序为:提取温度>提取时间>乙醇浓度>料液比,中华苦荬菜微波提取的最佳工艺条件为料液比为1∶20,乙醇浓度为70%,提取温度为90℃,提取时间为5min。与常规提取法相比,微波辅助提取技术具有提取时间短、提取率高等优点。
Taking Ixeris chinensis（Thunb.）Nakai as material,the rate of falconoid extraction indicators as the evaluation standard,and the effects of the feed-liquid rate,ethanol concentration,extraction temperature and time on the total falconoid contents were studied by single factor and orthogonal test in order to investigate the extraction process conditions of by microwave from I.chinensis.The results showed that the influence of factors on the extraction rate of falconoid was the order of extraction temperature extraction time ethanol concentration the feed-liquid rate,and the optimal microwave extraction condition of falconoid from I.chinensis by microwave was as follows：the feed-liquid rate was 1∶20;the ethanol concentration was 70%,the extractive temperature was 90℃ and the extractive time was 5 min.This extracting technology of falconoid by microwave was found to be a rapid and efficient extraction method with short time and high production yield compared with conventional extraction.
