The aim of this study was chemical analysis of phenolic compounds, as well as mineral nutrients in pulp and peel obtained from Balkan indigenous apple and pear cultivars. Phenolic composition assesed by means of HPLC-DAD and spectrophotometric methods varied significantly between the cultivars for both peel and pulp. Among apples Mekica cultivar had the highest total phenolic content while Šećerlija and Zlatna Parmenka had the lowest. In the case of pear samples the principal source of total phenolic content was Crna Takiša while their minimum was recorded for Bela Arapka. In most of the investigated samples chlorogenic acid in apples and arbutin in pears were major detected polyphenolic compounds. With regard to mineral analysis K was the most abundant followed by P, Mg, Ca and S. Iron was the dominant microelement in apple peel and pulp samples, while in pear samples the principal microelement was B. Obtained results provide detailed information on chemical composition of tested apple and pear cultivars and therby could encourage their wider cultivation and consumption.
