The objective of this work was to investigate relative antioxidant performance of seven different walnut (Juglans regia L.) genotypes including KZ7, KZ9, KZ15, OR126, Sebin, Pedro and Chandler grown on the Agricultural Research Center of West Azerbijan province, Urmia, Iran. Phenolics, flavonoids and antiradical capacities in hull and kernel were analyzed. The kernel of Pedro (66.55±4.98 mg/g of GAE) and hull of Sebin (122.26±1.34 mg/g of GAE) showed the highest value for phenolic compounds. The highest flavonoid compound was obtained in the kernel of KZ7 (13.57±2.27 mg/g of CEs) and hull of the Sebin (49 ±3.17 mg/g of CEs). Phenolics analysis was performed by High performance liquid Chromatography (HPLC) and 10 compounds were identified and quantified including ascorbic acid, gallic acid, rutin, caffeic acid, p-hydroxy benzoic acid, vanillic acid, p-cumaric acid, syringic acid, ferulic acid and sinapic acid. In hull extracts, the highest phenolic contents was found in KZ9 (gallic acid), KZ7 (rutin and sinapic acid) and KZ15 (p-hydroxy benzoic acid) while in kernel extracts, KZ9 (syringic and gallic acids), Chandler (sinapic acid) and KZ7 (p-cumaric and ascorbic acids). On the basis of the presented results, Iranian walnut genotypes could be considered as potential sources of natural antioxidants.
