Objective: To optimize extraction technology of Huangqi Jianzhong granules. Method: Water extraction technology was optimized by orthogonal design method and response surface method with yield of paeoniflorin and dry extract as indexes.Effects of the amount of water
extraction time and times on extraction technology of Huangqi Jianzhong granules was investigated
and extraction effect of this two methods was compared in order to choose the better one
transfer rate of paeoniflorin of 87.4%. Result: Optimum extraction procedure was:extracted 3 times with 8 folds of water
1 hour each time. Conclusion: This process was simple
economical
practical and suitable for extraction of active ingredients from Huangqi Jianzhong granules.
