Abstract : The antioxidant capacity of five Mangifera indica cultivar extracts (Heart, Dove, Magdalena River, Cinnamon and Jobo) was studied by determining the ?-carotene content, phenols, ascorbic acid and free radical scavenging capacity of 2,2-difenil-1-picrylhydrazyl (DPPH). We assessed the antioxidant capacity of the cultivars in a lipid matrix, comparing it with that of the commercial antioxidant butylhydroxyanisole (BHA). The IC-50 of the free radical scavenging capacity for the Jobo variety was 0.776; the best result using a simple regression model (R2=99.58). This variety showed a higher antioxidant activity with an extract concentration of 70.35 mg mL-1, verified by a phenol content of 208.80 mg L-1 of gallic acid. Furthermore, the Jobo variety had the highest concentration of ascorbic acid with 9,730.07 mg kg-1, while the Magdalena River variety showed the highest percentage of ?-carotene discoloration inhibition (46.53%). The Jobo variety provided the best performance in the food matrix using 1,000 mg kg-1 of extract, achieving the same effect of BHA over the allowable concentration (175 mg kg-1).
