Abstract :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 insert ignore into journalissuearticles values(Turkey); and 5 standard cultivars were determined. In local cultivars, antioxidant activities insert ignore into journalissuearticles values(μmol Trolox equivalent insert ignore into journalissuearticles values(TE); antioxidant g fresh weight insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(‘Royal Gala’); and 0.29 insert ignore into journalissuearticles values(‘Granny Smith’ and ‘Pink Lady’); in fruit flesh and between 0.27 insert ignore into journalissuearticles values(‘Jonagold’); and 0.61 insert ignore into journalissuearticles values(‘Royal Gala’); in fruit flesh + skin tissue. In local cultivars, total phenolics insert ignore into journalissuearticles values(Gallic acid equivalent insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(‘Royal Gala’); and 124.64 insert ignore into journalissuearticles values(‘Jonagold’); in fruit flesh and between 102.73 insert ignore into journalissuearticles values(‘Summerred’); and 198.72 insert ignore into journalissuearticles values(‘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 ‘Hemşin Elması’ had greater values of both parameters in fruit flesh than in fruit flesh + skin tissue.
