Quinoa is a pseudo cereal plant with high nutritional values. Recently, it was cultivated in iran because of the water crisis. This study aimed to assess the physicochemical and antioxidant properties of quinoa cultivated in iran for the first time. The macronutrients and energetic value, polyphenol, total phenol content and DPPH of quinoa were measured. Some B group vitamins, the free fatty acid profile and trace elements were assessed. Trace elements were also evaluated by iCP. The amounts of dry matter, protein, fat, ash, and available carbohydrates were, 90.30±0.89, 16.30±1.52, 6.09 ±0.30, 4.43±0.47, and 73.14±1.59 %, respectively. The total bacterial count of quinoa was 5.22±0.23 (LOG10 CFU/g). Escherichia coli and sulphite-reducing Clostridia were lower than 1.0 (LOG10 CFU/g). Salmonella was absent in all samples. According to the DPPH method, the half-maximal inhibitory concentration (iC50) of quinoa seed was approximately 6232.0 mg/L compared to the equivalent Gallic acid as a standard (iC50: 184.15 µg/mL). Quinoa seed contained the highest niacin level (0.881 mg/100g) among the vitamin B groups. The amino acid profile analysis revealed the highest contents of glutamic acid (1.230 g/100g) and lysine (3.08 g/100g). The linoleic acid content was 63.5 g/100g (fat). The concentrations of minerals including calcium, magnesium, and potassium, were 0.07, 0.086 and 0.35 g/100g (dw), respectively. Quinoa is a valuable nutritional product that can provide health benefits to humans, mainly because of its linoleic acid content.
