The antioxidant potency of various extracts and fractions from Chenopodium quinoa and Amaranthus sp. was evaluated using three established methods, specifically the DPPH scavenging activity, FRAP, and P-carotene bleaching assays. Satisfying results were obtained, which lead to expect the use of these seeds as health-promoting ingredients. The antioxidant activity was less correlated to the phenolics content suggesting that non-phenolic compounds might play major free radicals scavenging activity in studied plant materials.
