Optimization the Preparation Process of Paeonia lactiflora Based on Effective Components and Contents
Abstract
(AHP) was used to determine weight coefficients of eight effective components, and a multi-index evaluation system was established using a
weighted comprehensive scoring method. Single-factor experiments screened the optimal ranges of material-liquid ratio, ultrasonic time, and
ethanol concentration, followed by star-point design response surface methodology for three-factor optimization. The quadratic polynomial
model fit well (R²=0.8198). Optimal parameters: solid-liquid ratio 1:25 g/mL, ultrasonic time 69 min, ethanol concentration 83%, with a
predicted comprehensive score of 90.9. Three validation experiments averaged 90.8 (RSD=0.38%), deviation of 0.30%, confirming high
model reliability. This method combines AHP weights with response surface methodology, overcoming single-indicator limitations and
improving extraction efficiency and stability.
