Nutraceutical and Functional Properties of Peel, Pulp, and Seed Extracts of Six ‘Köhnü’ Grape Clones

Grape production has a long history in the Elazig province and surrounding vicinity produced grapes have been used for table consumption also processed into traditional beverages, Şıra (special non-alcoholic grape juice) wine. In province, main cultivars are ‘Ağın Beyazı’, ‘Öküzgözü’, ‘Boğazkere’, ‘Şilfoni’, ‘Tahannebi’, ‘Köhnü’. Among them, ‘Köhnü’ cultivar is highly preferred by consumers due to its black color perfect berry characteristics. The grown centuries different parts of shows great variability most morphological biochemical present study, we aimed determine traits six clones sampled from Elazığ. cluster weight was found between 334–394 g. highest total phenolic content observed seeds followed peel pulp samples. seed extract Clone 2 had at 254 mg gallic acid equivalent/100 g fresh weight. results showed that peel, pulp, samples considerable amounts antioxidant components determined DPPH (1,1-Diphenyl-2-picryl-hydrazyl), FRAP (ferric reducing power), TEAC assays might be rich sources natural antioxidants. clones, 3, 6 differed others respect weight, concentrations content, activity. implied all could potentially as readily accessible source antioxidants possible pharmaceutical supplement.
