Abstract

The polyphenolic of grape skins, pulps and seeds are potential source of natural antioxidant, which are receiving increased attention. In the present work, the total phenolics content (TPC), total flavonoids content (TFC), total flavanols content (TFAC), total anthocyanins content (TMAC) and antioxidant activity (DPPH, ABTS and FRAP) in different tissues of 4 table grapes cultivated in Chengdu plain, south of China, were investigated. In present study, expect TMAC was not be detected in seeds, and our results showed that seeds were the highest in polyphenolic content and antioxidant activity followed by skins, and then pulp. Besides, ‘Fenghou’ is richer in polyphenolic content than other three cultivars. Hence, ‘Fenghou’ extracts possesses higher free radical scavenging ability.
