Materials and Methods: Total phenolic compounds levels were determined by Folin-Ciocalteu method. Total flavonoid content was determined as AlCl3 complex and expressed as mg of quercetin equivalents (QE)/g dry extract and total proantocyanidins content was expressed as mg of catechin equivalents (CA)/g dry extract. In order to evaluated the antioxidant activity of the compounds, DPPH and FRAP assays were used. Results: The highest level of total phenols (156.42 mg GA/g DE), total flavonoids (130.94 mg QE/g DE) and total proantocyanidins (152.816 mg CA/g DE) were obtained in Akbari cultivar from Rafsanjan, followed by Badami-e-sefid and Ahmad aghaei. The lowest amount of total phenolic content (TPC), total flavonoid content (TFC) and total proanthocyanidin content (TPrAC) were found in Badami-e-sefid from Feizabad (128.140 mg GA/g DE, 93.176 mg QE/g DE and 118.870 mg CA/g DE, respectively). Also, a positive correlation (r2=0.9834) was found between antioxidant activity and total phenolic compounds. Conclusion: Pistachio increased their phytochemical compounds to contrast with abiotic stress. Our data could be useful for introducing special characteristics to the plants, and can be considered when planning a new breeding program or choosing a specific cultivar for a particular use.}, keywords = {Antioxidant activity,DPPH,Ferric reducing,Pistacia vera}, url = {https://ajp.mums.ac.ir/article_9385.html}, eprint = {https://ajp.mums.ac.ir/article_9385_8e7ae1bf22af58450d3983eb6a1f5e38.pdf} }
