槐米中芦丁的提取条件研究

Study on Conditions of Extracting Rutin from Flos SopHorae

目的:优化槐米的提取条件以提高芦丁的提取率。方法:以芦丁的精制品提取率为评价指标,对影响槐米提取率的各项因素(槐米形态、反应温度、pH值)进行实验分析,最后选出比较稳定、提取率较高的条件。结果:最佳条件为粗粉条件下,碱溶时pH值为9,酸沉淀时pH值为3,70℃时芦丁的提取率最高。结论:适宜的条件可提高槐米中芦丁的产率。

Objective：To optimize the extraction conditions of SopHora japonica in order to improve the extraction rate of rutin.Methods：With the masterwork of Rutin Extraction rate as the evaluation index,the rate of extraction of Flos SopHorae Immaturus various factors（sopHora flower bud morpHology,reaction temperature,pH value）and to analyze the experiment,finally choose the relatively stable,extraction rate is higher.Results：The best condition of coarse powder,alkali solution pH value is 9,acid precipitation pH value is 3,70 degrees of Rutin Extraction rate is the highest.Conclusion：Appropriate conditions can improve the yield of rutin.
