ABSTRACT: OBJECTIVE To optimize the processing technology of Fritillaria thunbergii（huibei）by response surface methodology combined with entropy weight method. METHODS The single factor experiment combined with Box-Behnken design was used to optimize the the processing technology, with five kinds of alkaloid (yibeissine, peimisine, peimine, peiminine, isobeta metrin ) as the inspection indicators, combined with the weight coefficients were calculated by entropy weight method. RESULTS The optimum extraction process was determined as following: crashing time for 95 seconds, material-to-ash ratio for 0.9%, sweating time for 5 hours, and drying temperature for 45℃. The RSD between the validation results and the predicted values is 0.5%.CONCLUSION This optimized processing technology is stable amd feasible, which can provide the scientific basis for quality control of huibei processing technology.
