    The present research work aimed to evaluate the antioxidant activity and antibacterial effect of the essential oil of Citrus sinensis peels variety Valencia Late. The extraction of the essential oil was carried out by steam distillation. The antibacterial effect was evaluated against the strains of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 12228 following the agar diffusion method and the antioxidant activity was determined by the DPPH radical method (2,2-diphenyl-1-picrylhydrazyl). It is a quasi-experimental and quantitative research work. For the results in the antibacterial effect, a nonparametric Kruskal Wallis test was used. Regarding the antioxidant activity in the essential oil of Citrus sinensis peels variety Valencia Late, the IC50 (minimum concentration necessary to inhibit 50% of DPPH) was determined by a linear regression adjustment. The results were illustrated using bar charts and box plots. It was concluded that the essential oil of Citrus sinensis variety Valencia Late exhibits antibacterial effects against the two strains tested and antioxidant activity against the DPPH radical.
