Objective:To optimize the extraction process of anthocyanins from purple potato.Method:Using ultrasonic assisted extraction method,the extraction time,liquid-solid ratio,ethanol volume fraction and ultrasonic power were investigated,and the extraction amount of anthocyanin was evaluated,the optimal extraction process was obtained by single factor experiment and orthogonal experiment.Result:When the ratio of liquid to solid was 1∶10(g∶mL),ethanol volume fraction was 70%,the ultrasonic power was 150 W and the extraction time was 30 min,the extraction amount of anthocyanins was the highest(60.8 mg/100 g).Conclusion:The extraction process was stable,and it was suitable for the extraction of anthocyanins from purple potato.
