Objective: To optimize extraction process of children Jianpi ointments by central composite design-response surface methodology. Method: Extraction technology of children Jianpi ointments was optimized by taking water volume and extraction time as independent variables
overall desirability value of extract yield and the content of hesperidin as evaluation index;Central composite design was adopted to design a two factors-five levels table and conduct test-screening
then quadratic polynomial fitting and depicting of 3D-response surface were performed
extraction process was selected by response surface methodology. Result: Optimal extraction technology was as follows:extracted twice with 21-folds of water
160 min per time.Under these conditions
average yield of hesperidin was 13.245 mg·g-1
average extract yield was 42.37%
bias between the observed and predicted value was 1.429%. Conclusion: This optimized extraction technology was stable and feasible
which could be as production process of children Jianpi ointments.
