In this study the pomological characteristics and antioxidant compounds of 13 genotypes of ber fruit collected from the Hormozgan province were evaluated. Ber fruits harvested at commercial maturity stage and their quantitative and qualitative characteristics were studied. The results showed that there is a significant difference between ber genotypes for these traits. The highest fruit and flesh weight, fruit diameter and fruit flesh percentage was related to genotype G3. The highest fruits and seeds were belonged to genotype G11. The level of total soluble solids (TSS), titratable acidity (TA) and TSS/TA ratio were higher respectively in the G9, G3 and G10 genotypes than others. Biochemical measurement results showed that the total phenolics and flavonoids content and antioxidant capacity of fruits is the highest in the genotype G5, while the highest amount of vitamin C obtained from genotype G4. Amount of catechin and quercetin of flavonoids were maximum, respectively in the genotypes G3 and G10. Positive correlation was observed between the amount of antioxidant activity with vitamin C, total phenolics and flavonoids content of ber fruit genotypes. Overall, the results of this study demonstrated that sensory attributes in the G10 and quantitative properties and antioxidant compounds in G3 genotype were higher and ber could be cultivated as a fruit with high nutritional values in the appropriate areas.

Abstract
In this study, the amount of total phenol, chlorogenic acid, catechin, quercetin, phloridzin, cyanidin and antioxidant activity of apple (Malus domestica) skin and flesh of six Iranian cultivars, including: ‘Golab Kohanz’, ‘Sib Torsh Dirras’, ‘Ghara Yapragh’, ‘Torkman’, ...

In this study, the amount of total phenol, chlorogenic acid, catechin, quercetin, phloridzin, cyanidin and antioxidant activity of apple (Malus domestica) skin and flesh of six Iranian cultivars, including: ‘Golab Kohanz’, ‘Sib Torsh Dirras’, ‘Ghara Yapragh’, ‘Torkman’, ‘Ghezel Alma’ and ‘Abbasi Mashhad’, and four commercial cultivars including: ‘Golden Delicious’, ‘Red Delicious’, ‘Braeburn’ and ‘Fuji’ was investigated. ‘Fuji’ had the highest amount of cyanidin 3-galactoside (3711.9 µg.g-1 fresh weight) and ‘Golab Kohanz’ had the greatest amount of quercetin 3-galactoside (3133.8 µg.g-1 fresh weight) and phloridzin in the skin (642.2 µg.g-1 fresh weight) and ‘Ghara Yapragh’ showed the greatest amount of flesh phloridzin (98.1 µg.g-1 fresh weight). ‘Abbasi Mashhad’ had the largest amount of flesh (484.3 µg.g-1 fresh weight) and the skin's (298.1 µg.g-1 fresh weight) chlorogenic acid, ‘Ghezel Alma’ had the greatest amount of catechin of skin (255.2 µg.g-1 fresh weight) and ‘Sib Torsh Dirras’ showed the highest catechin of flesh (76.9 µg.g-1 fresh weight). The regression analysis of total phenol and antioxidant capacity showed a positive correlation between the amount of total phenol and the antioxidant activity. The highest amount of total phenol and antioxidant activity in ‘Fuji’ was observed.
