Sacha Inchi oil was studied for its physicochemical characteristics, chemical composition, radical scavenging activity and storage stability. The fatty acid composition was studied by gas chromatography–flame ionization (GC–FID) and the analysis showed that the oil is highly enriched in α–linolenic (43.5%) and linoleic (39.6%) acids. The tocopherol content in the oil analyzed by high performance liquid chromatography/ultraviolet– visible detector (HPLC/UV–VIS) was also high (161.87 mg.100 g-1). Both DPPH and ABTS assays detected relatively high radical scavenging activity. After twelve months of storage, the oil showed relatively good storage stability. The results will help guide further investigation of the health benefits of Sacha Inchi oil for the population and the development of better edible oil products and nutraceuticals. Se ha estudiado las características físico-químicas, la actividad de captación de radicales y la estabilidad durante el almacenamiento de aceites de sacha inchi. La composición en ácidos grasos se estudió mediante cromatografía de gases (GC-FID) y mostró que el aceite es altamente rico en α-linolénico (43,5%) y linoleico (39,6%). El contenido de tocoferoles analizado mediante cromatografía líquida y detección mediante ultravioleta-visible (HPLC/UV-VIS) fue alto (161,87 mg.100 g-1). Los ensayos de DPPH y ABTS detectaron actividad captadora de radicales relativamente alta. Tras doce meses de almacenamiento los aceites mostraron una relativamente buena estabilidad. Los resultados ayudarán a orientar investigación adicional sobre los beneficios para la salud del aceite de Sacha Inchi para la población y al desarrollo de mejores productos de aceites comestibles y nutracéuticos
