Background : Apples have been known as nutritious and natural medicines. The aim of this study was to determine the amounts of nutrients compounds of golden and red delicious apples produced in Lorestan, Iran. Materials and Methods: Apple cultivars were harvested from different locations throughout Lorestan province in September 2008. The samples were dried at 80 º C for two days. The dry materials were grounded to analyse the elements. Phosphorous calcium, iron, and zinc and sodium and potassium were measured by spectrometry, atomic absorption and flame photometry, respectively. Other measured factors were energy, protein, carbohydrate, water, ash, and fiber. Results: The amounts of water, soluble solid products, ash, and fiber in red apples varieties were 78, 17.9, 1.44, and 0.72 percent, respectively. These values for golden delicious apples were 77, 16, 1.42, and 0.72 percent, respectively. Energy, sugars, and protein contents of red delicious apples were 73 calories, 18, and 0.27 g/100, respectively. These amounts for golden varieties were 83 calories, 20.6, and 0.2 g/100, respectively. K, Ca, P, Na, Fe, and Zn contents of red delicious apples were 63.8, 27.6, 9, 4.8, 0.24, and 0.14 mg/100, respectively. These values for golden delicious variety were 66.3, 27.7, 8.8, 4.5, 0.23, and 0.14 mg/100, respectively. Conclusion: Energy, carbohydrates, and calcium contents of apples varieties produced in Lorestan province were more than their contents in Iranian Food Composition Tables. However, their iron contents were less than it.
