Abstract: In order to solve the problem of insufficient extraction and low yield of ellagic acid through the single acid hydrolysis, we carried out some single-factor experiments and orthogonal experiments based on acid hydrolysis, considering the influence of different extraction temperatures, time and ethanol concentrations on the extraction rate of ellagic acid. By the spectrum scanning for granatum ellagic acid sample from ultrasonic extraction under UV spectrophotometry optimal conditions, and the comparing with standard ellagic acid calibration curve and content calculation, we obtained the results that showed the optimum ultrasonic extraction condition was: the best extraction temperature of 60℃, the concentration of ethanol of 40%, and the ultrasonic extraction duration of 40 minutes. The extraction rate of ellagic acid was up to 18.07%, which was increased by 4%, compared with single acid hydrolysis method.
