“Grape (Vitis sp.) is a natural source of phenolic compounds related to important health benefits. Polyphenols have been associated with the bioactive potential of grapes due to their antioxidant, anti-inflammatory, anticarcinogenic and antibacterial activities ( Bagchi et al.., 2000; Daglia, 2011; Rockenbach, Rodrigues, et al., 2011). Grape products, such as juice and wine, contain high amounts of polyphenols, in concentrations that vary according to the grape species, cultivar and derivative. Since wine is one of the most important sources of polyphenols in the human diet and it has a great distribution in several countries, grape polyphenols have mainly been evaluated in Vitis vinifera L. grapes, that is, those generally cultivated for wine production ( Kondrashov, Sevcík, Benáková, Kostírová, & Stípek, 2009). However, grape juice BYL719 is a natural and refreshing beverage, and its
peculiar taste and nutritional value has led to growing consumption worldwide. American varieties of Vitis
labrusca L. are widely cultivated in Brazil, mainly for juice production. The V. labrusca L. cultivars represent more than 80% of processed grapes, being also destined for the production of table wines and other derivatives such as vinegar, sweets and jams. In Brazil, the most commonly cultivated red grapes are Bordo, Concord and Isabel, which account for around 50% of the national grape production ( Nixdorf & Hermosín-Gutiérrez, 2010; Oliveira, Lopes, Haji, Moreira, & Miranda, 2009). Brazilian winery industries generate approximately 59 million kg of by-products that are generally used for agricultural composting. The bioactive potential of V. labrusca L. and its constituents have been previously Ceramide glucosyltransferase reported ( Nixdorf & Hermosín-Gutiérrez, 2010; Rockenbach, Gonzaga, et al., 2011; Rockenbach, Rodrigues, et al., 2011). Many studies demonstrated that agricultural and industrial residues of grape are attractive sources of polyphenols as natural antioxidants (Moure et al., 2001; Volf & Popa, 2004). Fruit industries utilize considerable amounts of vegetable material and produce large quantities of peel and seeds which could constitute major sources of phenolic compounds for fruit products such as grape juice. The by-products of viticulture, in particular grape peels and seeds, have been found to contain higher amounts of polyphenols than the edible portions.
