The aim of this study was to quantify the bioactive compounds content and the total antioxidant activity of 18 cultivars oftable grapes from the Active Germplasm Bank of Embrapa Tropical Semi-Aríd, located at the Experimental Field ofMandacaru, in Juazeiro, Bahia State, Brazil. The cultivars studied were: A dona, Benitaka, Brasil, Cardinal, Christmas Rose, Estevão Marinho, Frankenthal, Isabel, Isabel Precoce, Isaura, Liberty, Muscat Caillaba, Muscat Hamburg, Muscat Noir, Patrícia, Piratininga, Satum and Vênus

Sara Mesquita Street, 2270, ZIP Code 60511-110, Fortaleza,Ceará State, BrazilThe demand for natural and healthy food that offers benefits to consumer health greatly stimulates themarket of products such as grape and its derivatives. Currently, these products are consumed not only forits sensory qualities, but also as sources of compounds with antioxidant activity. The aim of this studywas to quantify the bioactive compounds content and the total antioxidant activity of 18 cultivars oftablegrapes from the Active Germplasm Bank of Embrapa Tropical Semi-Aríd, located at the ExperimentalField ofMandacaru, in Juazeiro, Bahia State, Brazil. The cultivars studied were: A dona, Benitaka, Brasil,Cardinal, Christmas Rose, Estevão Marinho, Frankenthal, Isabel, Isabel Precoce, Isaura, Liberty, MuscatCaillaba, Muscat Hamburg, Muscat Noir, Patrícia, Piratininga, Satum and Vênus. Bunches wereharvested when berries were ripe. After harvest, they were transferred to the Postharvest PhysiologyLaboratory, at Embrapa Tropical Semi-Arid. The variables analyzed were anthocyanins, yellowflavonoids, total extractable polyphenols content, as well as total antioxidant activity, using the ABTS andDPPH methods. Among the cultivars analyzed, Isabel Precoce showed the highest anthocyanins content(166.42 mg 100 g') and total extractable polyphenols (165.24 mg 100 g').The yellow flavonoids contentvaried from 2l.68 mg 100 g', in 'Muscat Caillaba', to 45.78 mg 100 g', in 'Isabel Precoce'. However,Benitaka, Christmas Rose, Estevão Marinho, Isabel, Liberty, Patrícia and Piratininga cultivars areequivalent to 'Isabel Precoce' for that characteristic. When the total antioxidant activity was determinedby the ABTS method, the cultivars Muscat Caillaba, Isabel Precoce and Christmas Rose showed thehighest average values: 9.68, 9.27 and 8.57 ~ Trolox. s' pulp, respectively. On the other hand, weidentified Christmas Rose, Frankenthal, Isabel Precoce, Muscat Caillaba, Muscat Hamburg, Muscat Noir,Patricia, Piratininga, Satum and Venus as cultivars that had the most relevant total antioxidant activity,through the DPPH method. The results suggested that the highIighted grape cultivars could be consumedin order to maintain good health and they could be inserted in breeding programs focused in obtainingcultivars with higher functional compounds content and total antioxidant activity.182
