Quinoa has gained an increasing interest in recent years due to its nutritional value as well as its antioxidant capacity and phytochemical content. The objective of this work was to determine the physico-chemical properties, vitamins (B1 , B2 , B3 and E) and the antioxidant activity of six ecotypes of quinoa (Chenopodium quinoa Willd) cultivated in three quinoa production zones in Chile (North Highlands, Center and Southern Chile). The samples are called Ancovinto and Cancosa from the North, Cáhuil and Faro from the Center, and Regalona and Villarica from the South. To evaluate the differences among ecotypes, an analysis of variance was conducted using one-way ANOVA and the least significant difference (LSD) test. Proximate analysis of quinoa seeds including moisture, crude protein, fat, crude fiber, ash and available carbohydrates for the six ecotypes showed differences among samples (p-value
