【摘要】 [Objective] To optimize the ultrasonic extraction process of total flavonoids from litchi pericarp.[Method] The total flavnoids was extracted by ultrasonic method,and the optimum extraction process was optimized with orthogonal design based on single factor test.[Result]The optimum extraction conditions of flavonoids from litchi pericarp were as follows:alcohol concentration of 60%,solid-liquid ratio of 1∶50,extracting duration of 30 min,extraction for twice.Under these conditions,the extraction rate of flavonoids reached as high as 28.18 mg/g.[Conclusion] Ultrasonic technology is convenient and effective for the extraction of total flavonoids from litchi pericarp,which lays foundation for its further development.
