Background and aims: Walnuts are a good source of essential fatty acids and tocopherols. Chemical compounds especially fatty acids and tocopherols are different depending on the genotype and environmental conditions. This study aimed to study the fatty acid compositions and pellicle antioxidant properties of different Persian walnut (Juglans regia L.) genotypes. Methods: In this experimental study, the fatty acid compositions of six walnuts (Juglans regia L.) genotypes (K1, G1, B1, K2, K3, B2) were collected from different areas of Koliaie in Kermanshah. Fatty acid compounds were analyzed using gas chromatography coupled to a flame ionization detector. Also, (2, 2-diphenyl-1-picrylhydrazyl) DPPH radical scavenging activity was used to analyze antioxidant properties. Results: Total oil ranged from 63.3 to 78.5%. Polyunsaturated fatty acids (PUFAs) included the most important group of fatty acids in the studied oil of different genotypes that they were in the range of 57.6% to 70.20%. The highest range of PUFA in the B2 genotype was observed. B2 genotype showed more radical than the other genotypes in collection activities (P<0.05). Conclusion: These results demonstrate that fatty acid composition is genotype dependent. Pellicle is replete of antiradical and a necessary protecting layer that fatty acids particular PUFA protect against radicals.
