摘要
目的研究白花蛇舌草中槲皮素的最优提取工艺。方法以液相色谱法测定,在单因素试验基础上,采用正交试验分析,优化提取工艺。结果白花蛇舌草中槲皮素的最佳提取工艺为甲醇浓度100%,料液比1∶60,提取液盐酸比100∶5,回流时间0.25h。结论该方法在节约成本的前提下最大化提取效率,可以为白花蛇舌草中黄酮类化合物的开发提供有价值的参考。
OBJECTIVE To study the optimum extraction technology of quercet in from Hedyotis chinensis.METHODS The extraction process was optimized by orthogonal analysis on the basis of single factor test.RES ULTS The optimum extraction process of quercetin from Hedyotis albicans was as follows:reflux time 15min,material to liquid ratio 1∶60,methanol con centration 100∶5,HCl/liquid ratio 100∶5.CONCLU SION This method maximizes the extraction efficiency under the premise of saving cost,and can provide valuable reference for the development of flavonoids in Sargassum chinensis.
