Antioxidant Properties of Some Traditional Iranian Edible Fruits Growing Wild in Lorestan Province in the Western Iran

Background and Aim : The aim of this study was to determine the antioxidant properties of Ziziphus Nummularia (ZN), Crataegus spp (CS) (red), Crataegus spp (CS) (yellow) , Eremurus Spectabilis (ES), and Berberis Integerrima (BI) which grow in the west of Iran. Materials and Methods : The free radical scavenging ability, total antioxidant capacity, phenol and flavonoid contents were measured using the 2, 2 diphenyl-1-picrylhdrazyl (DPPH), phosphomolybdate, Folin-Ciocalteu, and Zishen methods, respectively. Results : The total antioxidant capacities of ZN , CS (red), CS (yellow), and BI, were 0.93±1.15, 1.01±1.14, 1.42±3, and 3.36±4.84 (µmol ascorbic acid/gram of dry extract), respectively. Total flavonoid contents of ZN , CS (red), CS (yellow), and BI were 0.46±0.14, 0.98±0.17, 1.25±0.12, and 3.55±1.80 (mg quercetin/gram of dry extract), respectively. Total phenol content of the extracts ranged from 255.96±78.17 ( ZN ) to 5128.04±501.61 ( CP yellow) mg of gallic acid/gram of dry extract. The IC 50 value was lowest (3892.25±1298.51 µg/ml of extract) for CP (yellow) and highest (5571.35±31.06 µg/ ml) for CP (red) . Conclusion : The results of this study indicated that all the samples including were rich in phenolic and flavonoid contents.
