The paper presents data on the concentration of some mineral bio elements in native apple varieties: Champagne, Double red, Florina, Jonathan, Rennet and Wagener. The aim of this research was at estimating the mineral supply in daily diet and the possibility of using them as a supplementary source of essential microelements. The total amount of bio metals: iron, manganese, zinc and copper, were determined by flame atomic absorption spectrometry after samples calcination and ash extraction with HNO3. The experimental results reveal important contents in essential micronutrients, their distribution in analysed fruits present the following trends: Fe (III)> Mn(II)> Zn(II)> Cu(II). The results made us consider that these traditional fruits can be used as additional source of mineralizing bio elements in daily diet.
