Abstract
Pistachio nuts are rich sources of nutrients which are essential for human wellbeing. In the present study we investigate the variation of oil, protein, total phenol, mineral contents, and antioxidant activity of twenty rare Persian pistachio nuts and exocarp layer. Among the 20 pistachio genotypes, in seeds Mn concentration was varied from 5.73 to 17.33Â mg/kg; Fe ranged from 17 to 62.4Â mg/kg; Zn varied from 6.76 to 30.3Â mg/kg; Na ranged from 0.06 to 0.126%; K varied from 0.68 to 1.35%; P varied from 0.42 to 0.73%; N ranged from 2.6 to 4.29%; Mg varied from 0.11 to 0.17%, Ca varied from 0.23 to 0.47%, oil ranged from 47.94 to 57.29% and protein ranged from 16.26 to 25.5%. The G3 genotype had the highest total phenol content (35.64Â mg GAEs/g) and antioxidant activity (90.55%) in exocarp layer and oil content in seeds (57.29%). The highest phosphorus (0.73%) in exocarp layer and phenol (4.2Â mg GAEs/g) contents in seeds were observed in G19. According to the correlation analysis, there were a correlation between total phenol (in exocarp layer) and oil contents gain with some values; these two values had a significant correlation with PC1. Cluster analysis separated the genotypes into three groups considering all measured Values.
