Abstract:
Objective To optimize the extraction process of Paeoniae radix alba. Methods Extraction rates of paeoniflorin and total glucosides from Paeoniae radix alba and yield of dry extract were served as research indexes. Extraction process was optimized by central composite design-response surface methodology. Results Optimum condition of extraction technology was to extract 2 times with 9-fold of 85.00% ethanol for 100 min each time. Results of the three batches of confirmatory test were accordant with the predicted values. Conclusion The observed and predicted values were close to each other,and the optimum formulation by CCD-RSM was successful. The established model has a reliable predictability. The optimum extraction process is reasonable,stable and feasible.
