In this study some selected chemical properties such as total soluble solids, pH, total acidity, formalin index, reduced sugar content and ascorbic acid of major sour cherry cultivated grown in different provinces of Iran corresponding were investigated.  Minerals K+, Na+, Ca2+, Mg2+, Cu2+, Fe2+ and Zn2+ were determined by graphite furnace atomic absorption spectrophotometer. The result showed that some chemical properties of Sour cherry such as total soluble solids, pH, total acidity, formalin index content, reduced sugar content and ascorbic acid, were within the range of 12.4–17.4 g/100ml, 3.05–3.78, 0.5–1.1g/100ml, 4.09-6.01 g/100g, 3.80–5.49 g/100g, 3.59–5.06 g/100g, respectively. Fe2+ and Ca2+ were significantly higher than other minerals (K+, Na+, Mg2+, Cu2+ and Zn2+) in major varieties of sour cherry. In addition, the average concentration of Ascorbic acid, TA, total soluble solids, pH, reduced sugar and formalin index were respectively 3.36 g/100g, 0.76 g/100ml, 14.77 g/100ml, 3.36, 4.70 g/100g and 4.44 g/100g.
