Pomegranate (Punica granatum L.), Lythraceae, is mainly grown in Mediterranean region. It is one of the major cultivated productions of Iran, which have been used in folk medicine for many centuries. It has been proved that pomegranate has a high antioxidant activity and is effective in the prevention of atherosclerosis. This study compares the antioxidant activity, total phenolic and flavonoid contents of nine different pomegranate cultivars grown in Iran. Aqueous solutions of known Fe(+2) concentration, vitamin E, vitamin C, gallic acid and catechin were used for calibration. The results showed that Sour summer pulp cultivar had the most antioxidant effect with significant difference with the other cultivar (p < 0.05) which can be introduced as a potent source of natural antioxidants, and the peel of three cultivars (Sweet saveh malas, Sour summer and Black peel) as a suitable source for extraction and purification of phenolic and flavonoid compound. The antioxidant capacity of pomegranate peel extract is 10 times higher than the pulp extract.
石榴（Punica granatum L.），千屈菜科，主要生长在地中海地区。它是伊朗的主要栽培作物之一，在民间医学中已被使用了许多世纪。已证明石榴具有高抗氧化活性，对预防动脉粥样硬化有效。本研究比较了伊朗种植的九个不同石榴品种的抗氧化活性、总酚和黄酮含量。使用已知Fe(+2)浓度的水溶液、维生素E、维生素C、没食子酸和儿茶素进行校准。结果表明，酸夏果肉品种具有最强的抗氧化作用，与其他品种有显著差异（p < 0.05），可作为天然抗氧化剂的有力来源，三个品种（甜萨韦马拉斯、酸夏和黑皮）的果皮可作为提取和纯化酚类和黄酮类化合物的合适来源。石榴皮提取物的抗氧化能力比果肉提取物高10倍。
