There are some investigations regarding the physical and chemical properties of sweet cherry (Prunus avium L.) fruits, mostly their antioxidant capacity, phenol, ascorbic acid, as well as anthocyanin contents. Only little is known about the mineral content of sweet cherries. In this work we studied the 'Sweetheart' cultivar from Cova da Beira (Portugal), as this fruit is a rich source of nutritional components. Therefore, the mineral content of 'Sweetheart' cherry was studied. Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for the determination of minor and major elements. Prior to ICP-AES measurement, the samples were mineralized with a mixture of HNO3 and H2O2. Based on obtained results the content of minor elements was (Cu) 0.107, (Fe) 0.325, (Mn) 0.204 and (Zn) 0.090 mg 100 g-1. The concentrations of major elements were (Na) 0.629, (Ca) 16.0, (Mg) 24.0, (P) 23.6 and (K) 523 mg 100 g-1. For Mg and K, 'Sweetheart' cherry presented higher concentrations than literature: (Mg) 11.0 and (K) 222 mg 100 g-1. And similar concentrations were assessed for Cu, Fe, Zn, P and Ca: (Cu) 0.060, (Fe) 0.36, (Zn) 0.070, (P) 21.0 and (Ca) 13 mg 100 g-1. The results suggested that 'Sweetheart' cherries are rich in various essential elements, with main emphasis for K and Mg, and might be considered as an important dietary mineral enrichment for individuals deficient in mineral elements.
