    The process of extracting palm hearts from Euterpe precatoria Mart., 'huasaí,' kills the palm tree. This produces agro-industrial byproducts that should be utilized as an alternative for the root. Objective: To compare the antioxidant activity of the ethanolic extract from the root and fruit of Euterpe precatoria Mart., 'huasaí,' from the province of Maynas, relative to the species native to Chanchamayo. Methodology: The research design was quasi-experimental. The content of total phenols was determined by the Folin-Ciocalteu method, and antioxidant activity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Results: For antioxidant activity, linear regressions were used to obtain values for the half maximal inhibitory concentration (IC50). The 'huasaí' root from Chanchamayo and Maynas obtained an IC50 of 3.28 µg/mL and 3.86 µg/mL, respectively. The antioxidant activity measurements were contrasted using analysis of variance, Tukey's test (p<0.05), and the Student's t-test. Significant differences were found at the 5% level between the groups from the two provinces and for the three samples. Conclusion: The ethanolic extract from the root, epicarp, and mesocarp of the 'huasaí' fruit from Chanchamayo had greater antioxidant activity than the ethanolic extract from all the Maynas samples.
