| Abstract: | OBJECTIVE： To optimize the ultrasonic extraction technology of total alkaloid from Fritillaria thunbergii. METHODS： Extracting time, ultrasonic power and liquid-solid ratio were selected as casual factors, based on single-factor experiments, three-factor-three-level Box-Behnken experiment design method was applied, and the extraction rates of total alkaloid were used as response values for response surface methodology （RSM） analysis. RESULTS： The optimum conditions of ultrasonic extraction were as follows： extraction time of 48 min, ultrasonic power of 420 W, and liquid-solid ratio of 6.6 （mL：g）. Under these conditions, the extraction rate of total alkaloid was 0.168 5%. CONCLUSION： The extraction process optimized by RSM analysis is simple and more convenient for extracting total alkaloid from E thunbergii. |
