摘要
目的:对山楂叶总黄酮的制备工艺进行研究,并以山楂叶总黄酮的收率为指标,筛选出最佳的工艺。方法:采取渗漉的方法对山楂叶中总黄酮进行提取。结果:山楂叶渗漉收集乙醇10倍量,渗漉速度为5ml/min·kg,醋酸乙酯每次用量为0.7倍时山楂叶总黄酮的收率最好。结论:采用该工艺可达到对山楂叶总黄酮提取的目的。
Objective:To screen out the optimal technical conditions by doing a research on the preparation technology of total flavonoids in hawthorn leaves with the yielding rate of total flavonoids as index.Methods:The total flavone was extracted from the hawthorn leaves by using filtration.Results:The yielding rate of the total flavone in hawthorn leaves was the highest when the volume of alcohol filtrate collected was 10times with the filtering speed being 5ml/min·kg and the volume of acetic ether being 0.7times.Conclusion:The technical conditions studied can fulfill the purpose of extracting the total flavone in the hawthorn leaves.
