Apple is a fruit that is frequently consumed in daily diet and is very useful for human health. In this study, seven apple cultivars grown in Posof district in Ardahan province, including red-fleshed ‘İçi Kırmızı’ and ’Japon apples’ were investigated. ’Japon apple’ was found to have the highest values of total phenolic and ascorbic acid contents. The highest content of chlorophyll a (1.14 μg/g) was measured in ‘Mahara apple’, while the highest contents of chlorophyll b and total carotenoids (1.22 and 0.70 μg/g, respectively) were also observed in ‘Japon apple’. All the fruits and leaves of the apple cultivars, used in this study exhibited differential antioxidant and antibacterial effects. Except for ‘Şeker apple’, all methanolic leaf extracts exhibited inhibitory effects on Saccharomyces cerevisiae. In addition, the strongest antimicrobial activities were observed in ‘Japon apple’. While none of the doses of aqueous fruit extracts showed antimutagenic activities, different doses of the methanolic leaf extracts of the samples exhibited antimutagenic effects.

苹果是一种日常饮食中经常食用的水果，对人体健康非常有用。在这项研究中，调查了七个在Ardahan省Posof区种植的苹果品种，包括红肉“İçiKırmızı”和“ Japon苹果”。发现“ Japon苹果”的总酚和抗坏血酸含量最高。在“ Mahara苹果”中测得的叶绿素a含量最高（1.14μg/ g），而在“ Japon苹果”中测得的叶绿素b和总类胡萝卜素含量最高（分别为1.22和0.70μg/ g）。本研究中使用的所有苹果品种的果实和叶子均表现出不同的抗氧化和抗菌作用。除“苹果”外，所有含甲醇的叶提取物均对酿酒酵母具有抑制作用。。此外，在“日本苹果”中观察到了最强的抗菌活性。虽然没有剂量的含水水果提取物显示出抗诱变活性，但是不同剂量的样品的甲醇叶提取物显示出了抗诱变作用。
