Backgrounds Quinoa (Quino Chenopodium.Willd ) is attended due to its high nutritional value recently. Nutrients of Quinoa including amino acids ,antioxidant compounds ,essential fatty acids, minerals and vitamins led to research on the characteristics of this plant. While few studies have been done in Iran on characteristics of Quinoa.Materials and Methods To assess the nutraceutical potential of quinoa, the antioxidant capacity of quinoa leaves and seeds was investigated. The antioxidant activity against DPPH radicals is highly depends on the phenolic content of samples. In this research, using high performance liquid chromatography (HPLC), the ingredients of seed and leaf extracts were separated and identified. In addition, its antioxidant properties were measured by the evaluation of DPPH free radical scavenging and were used to measure the content of phenolic compounds by Follin-Ciocalteu method.Results Total phenol content in the seeds and leaves extract of quinoa, 54.4 and 76.3 (mg gallic acid per gram of extract) respectively and flavonoids in extracts of quinoa seeds and leaves 26.3 and 36.7 (mg quercetin per gram of extract) respectively were obtained. Analysis of variance showed that the concentration of synthetic antioxidant have significant effect on DPPH free radical scavenging (P
