摘要: 以乙醇和水为提取溶剂,选择根黄分散片提取物最佳的提取工艺。本试验采用不同浓度(40%、50%、60%、70%、80%、90%和100%)的乙醇和煎煮法分别提取,以黄芩苷得量和提取物得率为指标确定其最佳提取工艺。根黄分散片的最佳提取工艺为70%乙醇渗漉提取,药渣每次加10倍量水,煎煮2次,时间分别为2、1 h。先用70%乙醇进行渗漉提取,再水煎提取,此工艺简便可行,适于大规模工业化生产。

Abstract: The alcohol and water were used as solvent to optimize the best abstraction technique of Genhuang dispersible tables. In this experiment,the chinese herbs were abstracted with the different ethanol concentrations (40%, 50%, 60%, 70%, 80%, 90% and 100%) and water. The amount of baicalin and the extract rate were used as the index of the best abstraction technique. The best extraction technologic conditions were as the following. 70% ethanol was used to abstract according to percolation method. The gruffs were added ten times amount of water and extracted two times. They were two hours and one hour. After 70% alcohol was used to extract according to percolation method, we extracted the remaining gruffs according to decocting method. This process is simple and feasible, and it is suitable for industrialized large-scale manufacture.
