Arezoo Pourali, Mohammad Afrouziyeh and Sima Moghaddaszadeh-ahrabi

Total phenols of grape pomace were determined using the Folin-Ciocalteu method. Total phenols of the grape pomace were extracted with aqueous ethanol (80 % v/v) using a pomace-to-solvent ratio of 1:4 (w/v). Total phenolic content of grape pomace was 8.33 mg tannic acid equivalent/g. Grape pomace extract was rich in total phenolic content showed its potential for antioxidant activity and could be further evaluated as dietary supplements.
