摘要
目的 :研究赤土茯苓中总黄酮的提取工艺。方法 :采用正交试验设计 ,用三氯化铝、醋酸钾显色 ,紫外分光光度法测定总黄酮含量。结果 :最佳提取工艺为 8倍量 80 %的乙醇 ,回流提取 2次 ,每次 1h ,总黄酮得率高 ,提取率可达 90 %。结论 :本提取工艺可行。经济、省时、回收率高。
Aim To study the best conditions of extraction techniques for general flavonoids (GF) in Smilax glabra.Methods The best conditions of extraction technique for GF were optimized with orthogonal experiment.Developed by alminumtrichloride and potassium acetate, determination of GF with UV-spectrophotometry was made.Results The best conditions for the extraction techniques of GF were:80% alchohol which is 8 times of the medicine amount,reflux extracting two times,one hour per time.The yield of GF was high.Conclusion The extraction techniques are feasible.
