Özet

In this study, antioxidant activity and total phenolics in fruit flesh and fruit flesh + skin tissue of local apple cultivars encountered along the coastal zone of Northeastern Anatolia Region (Turkey) and 5 standard cultivars were determined. In local cultivars, antioxidant activities (mu mol Trolox equivalent (TE) antioxidant g fresh weight (fw)(-1)) varied between 0.17-1.70 in fruit flesh and between 0.35-1.55 in fruit flesh + skin tissue; in standard cultivars, the values varied between 0.24 ('Royal Gala') and 0.29 ('Granny Smith' and 'Pink Lady') in fruit flesh and between 0.27 ('Jonagold') and 0.61 ('Royal Gala') in fruit flesh + skin tissue. In local cultivars, total phenolics (Gallic acid equivalent (GAE) kg fw(-1)) varied between 53.26- 00.54 in fruit flesh and between 89.32-406.91 in fruit flesh + skin tissue; the values in standard cultivars varied between 56.30 ('Royal Gala') and 124.64 ('Jonagold') in fruit flesh and between 102.73 ('Summerred') and 198.72 ('Jonagold') in fruit flesh + skin tissue. Present findings revealed that local cultivars generally had 3-4 times greater antioxidant activity and total phenolics than the standard cultivars. Fruit flesh + skin tissue generally had greater antioxidant activity and total phenolics than the fruit flesh alone. However, the local apple cultivar of - 'Hemsin Elmasi' had greater values of both parameters in fruit flesh than in fruit flesh + skin tissue.
