Abstract

Plant polyphenolic compounds have been extensively studied and their antioxidant activity has been identified in several agricultural by- products, such as grape pomace. Grape seed in pomace is a good source of pro-anthocyanidins. Beside the seeds, grape skins in pomace represent a potentially important global source of trans-resveratrol. Trans-resveratrol, as a biologically active compound is one of the secondary plant metabolites, (Balasundram et al., 2006).
