Microwave Extraction of Polyphenol from Pomegranate Seed

Abstract

The effects of different synthetic conditions on the yield of polyphenols in pomegranate seeds were studied by controlling the solvent concentration, liquid / liquid ratio and microwave heating power by microwave heating method using pomegranate seed as raw material and ethanol as solvent. The results showed that the yield of pomegranate seed polyphenols was 3.14% when the solvent concentration was 40%, the ratio of material to liquid was 1:20 and the power was 400 W.
