Background and Objective: Pomegranate is an attractive deciduous and somewhat thorny large shrub or small tree (Punica granatum L.) belonging to the family Punicaceae, native to semitropical Asia (Iran ) and naturalized in the Mediterranean region in very early times. The edible part of the fruit contains considerable amounts of sugars, Vitamins, Polyphenols, Polysaccharides and Minerals. The physico-chemical properties of 8 Pomegranate varieties (collected from different provinces of Iran) and corresponding juices where investigated. Materials and Methods: The major minerals index (Mn,Cu,Fe,Zn,Pb,Cd,K,Na,Ca and Mg) were determined by Atomic absorption spectrophotometer. Acidity index was determined by potansiometer, SCC index was determined by refract meter and pH index was determined by pH meter. vitamin C index were determined by titrimetric method and total sugar was determined according to AOAC method. Results: It was perceived by using an atomic absorption spectrophotometer, the quantities of K, Na, Ca and Mg were significantly higher than other minerals (Mn, Cu, Fe, Zn, Pb and Cd) in the fruit juices .In addition the average concentration of Vitamin C, TA, SSC, pH and acidity were respectively 0.25 mg/100g, 13.3g/l, 16.8°B, 3.7 and 0.97. Conclusion: The mineral contents were generally as the same that those established in Iranian national standardthe and codex standard for pomegranate. The study emphasizes that pomegranate fruits can be a good source of nutrients. Keywords: Pomegranate, Physical Specifications, Chemical Specifications, Atomic Absorption Spectrophotometer
