摘要
目的探讨亳菊叶总黄酮提取工艺。方法采用正交试验,考察乙醇浓度、料液比、提取时间及提取次数4个因素对亳菊叶总黄酮提取率及浸膏得率的影响。结果优选出总黄酮最佳提取工艺为8倍量70%乙醇,回流提取2次,每次1 h。结论该工艺可提高亳菊叶总黄酮的提取率。
Objective To study the extractive methods of total flavonoids in chrysanthemum leaves from Bozhou,Anhui province.Methods An orthogonal test was carried out to observe the influences of the alcohol concentration,material-liquid ratio,extraction hours,and extraction times on the extraction yield of total flavonoids,and extractum.Results The optimum extracting procedure for total flavonoids was as follows： extracting with 8 times 70% alcohol,2 times reflux,and 1 h per time.Conclusion The optimum extracting procedure can increase the extraction yield of total flavonoids from Chrysanthemum leaves in Bozhou.
