【Abstract】 Objective: To optimize the extraction process of total alkaloids from Hemerocallis fulva by response surface methodology. Methods: The factors and levels affecting the extraction process of total alkaloids from Hemerocallis fulva were selected by single factor experiment, and the extraction process of total alkaloids was optimized by Box-Behnken design. Results:The optimum extraction conditions of total alkaloids from Hemerocallis fulva were as follows: ethanol concentration was 75%,ultrasonic time was 15 min, solid-liquid ratio was 1: 10(g/ml), ultrasonic temperature was 35 ℃, and the total alkaloids extraction amount was 2.58 mg/g. Conclusion: The optimized extraction process of total alkaloids from Hemerocallis fulva is reasonable and feasible.更多还原
