Abstract
Aim To optimize the extracting techniques of Gongxuening granules.Methods The extraction technique was selected by orthogonal method,with the contents of Astragaloside Ⅳ as index,the influential factors for the extraction of effective ingredients that included the amount of adding water,length of decocting time and frequencies of decocting were studied.Results The optimal extraction is as follows:adding 8 times amount of water and boiling for 120 min each time,extracting two times in all.Conclusion The optimal extraction technique was stable and feasible.
