Red grapes are a better source of antioxidants. Although studies have reported the major antioxidant contents and activities of grape cultivars, but the literature lacks information on detailed antioxidant composition and capacities of grape cultivars grown with rain-shelter-cultivation in Chengdu plain, south of China. In the present study, the total phenolics content (TPC), total flavonoids content (TFC), total flavanols content (TFAC), total anthocyanins content (TMAC) and antioxidant activity (DPPH, ABTS and FRAP) were detected and the results will provide basic knowledge about antioxidants of six red skin grapes. The results indicated the content rank order as follow: seeds > skin > pulp. Furthermore, ‘Red Globe’, ‘Jintianmeizhi’ and ‘Hongbaladuo’ have more antioxidants than other cultivars. Our results will provide a basic theory basis for consumers and further utilization of antioxidants.
