摘要
为获得乙醇浸提法提取芒果叶黄酮类化合物的最佳条件,采用单因素实验得出基本工艺参数为:提取时间2 h,料液比1∶30,乙醇浓度70%,提取温度65℃。在此基础上通过正交实验设计优化提取条件,得到最佳提取工艺参数为:提取时间2 h,料液比1∶25,乙醇浓度70%,提取温度70℃,在此条件下芒果叶中总黄酮得率为5.02%。
In order to obtain the best conditions for extracting mango leaf flavonoids by ethanol extraction,single factor experiments were used to obtain the basic process parameters:extraction time 2 h,material-liquid ratio 1:30,ethanol concentration 70%,extraction temperature 65℃.On this basis,the extraction conditions were optimized through orthogonal experiment design,and the best extraction process parameters were obtained as follows:extraction time 2 h,material-toliquid ratio 1:25,ethanol concentration 70%,extraction temperature 70℃,under these conditions,the mango leaves The yield of total flavonoids was 5.02%.
