Abstract

Objective To establish a microwave-assisted extraction(MAE) method for the extraction of the naringin in Fructus Aurantii.Methods Various experimental conditions of MAE affecting extraction of naringin from Fructus Aurantii were investigated by orthogonal experiments,such as ethanol concentration,the microwave power,the liquid/solid ratio and the microwave-extraction time.Results The optimum conditions of MAE were obtained: ethanol concentration 40%,the microwave power 425W,the liquid/solid ratio 50 ml·g-1,the microwave-extraction time 4 min.With the optimized condition,the recoveries were from 96.8% to 102.4% and relative standard deviation(RSD) was 2.57%.Conclusion MAE for effective constituent from Fructus Aurantii by orthogonal experiments is suitable and feasible.Compared with Soxhlet extraction and Ultrasonic extraction,MAE is more rapid with higher efficiency.
