Abstract

Abstract:

The optimal microwave-assisted extraction processing of total polyphenols from Auricularia auricula was investigated by orthogonal experiments to explore the effects of microwave power, microwave treatment time, material-liquid ratio and ethanol concentration on extraction rate of total polyphenols. Results indicated that the optimal extraction processing parameters for total polyphenols from Auricularia auricula were microwave irradiation power of 450 W, microwave treatment time of 120 s, material-liquid ratio of 1:25 and ethanol concentration of 75%. The extraction rate of total polyphenols was up to 0.72% under the optimal extraction processing conditions.

Key words: Auricularia auricula, polyphenol, extraction technology, microwave
