Banana and plane are the most important fruits in world trade, behind citric plants. In this work we studiedthe antioxidant capacity of banana and plane varieties of fruits obtained from interspecies crossed varieties of Musa acumi-nataand Musa balbisiana, named Harton plane, Cavendish banana, and Manzano banana. With this purpose we evaluatedbanana and plane crude extracts using the ferrous ion oxidation with xylenol orange method, the thiobarbituric acid method,determination of antioxidant activity, and effect on superoxide anion and hydroxyl radical and the radicals generated by ul-traviolet light. The experiments showed that all extracts have the capacity to decrease the concentrations of lipid hydroper-oxides and malondialdehyde, produced in the lipid peroxidation process, in a manner comparable to that of other widely stud-ied antioxidants like melatonin and vitamin E. Moreover, all extracts had the capacity to inhibit the generation of superoxideanion, hydroxyl radical, and the radicals generated by ultraviolet light. When antioxidant activity was calculated, a value wasfound that was equivalent to a concentration of uric acid between 0.20 and 0.30 mM at the highest concentration of extractused, with uric acid being a potent antioxidant at 1 mM.
