Abstract

In the present study, some phenolic compounds of peel, total phenolics and antioxidant activity of peel and pulp of 13 native and imported apple cultivars growing in apple collection of Seed and Plant Improvement Research Institute (SPII) located in Kamal-Abad, Karaj, were studied. Different cultivars had significant variations regarding all measured compounds. Among the studied cultivars the peel of ‘Paeez-e Zard Mashhad’ had the highest content of chlorogenic acid and the peel of ‘Jeanne Hardy’ had the highest content of catechin, phloridzin and quercetin 3-galactoside. The highest content of cyanidin 3-galactoside found in the peel of ‘Idared’. The peel of ‘Delicious’ and the pulp of ‘Starkan Roj’ showed the highest content of total phenolics and antioxidant activity. The positive and significant relation was observed between total phenolics and antioxidant activity in peel (0.86**) and pulp (0.93**). Cluster analysis based on the antioxidant activity of the peel and pulp, classified the studied cultivars into 3 completely separate groups, with high, medium and low antioxidant activity. Interestingly, based on this grouping, 2 cultivars ‘Starkan Roj’ and ‘Shisheie-e Tabriz’, with having high content of antioxidant capacity were considered as very valuable cultivars regarding health benefits.
