Abstract
Extraction of phenolic compounds and quantification of the total phenol of grape pomace
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.
