The objective of this research work was to evaluate the antimicrobial effect of 2 oil sources against Staphylococcus aureus and Fecal Coliforms. For the oil extraction, the steam drag method was applied where 5000g of sample was used (muña, Eucalyptus leaves), in which the yield presented: muña 50ml = 0.9268%, eucalyptus 52ml = 0.9717%, a Physicochemical characterization whose result was: in muña oil: peroxide index: 0.75 (Meq / Kg), Iodine index: 6.87 (IV), Acidity index: 1.78 (% FFA), Refractive index: 1.486 (n), density: 0.898 (Kg / L). In eucalyptus leaves: peroxide index: 0.68 (Meq / Kg), Iodine index: 8.08 (IV), Acidity index: 1.82 (% FFA), Refractive index: 1.495 (n), density: 0.845 (Kg / L). Inhibition halos were determined in millimeters (mm), with muña oil in dilutions at 25, 50 and 75% against Fecal Coliforms, where it was at 25%: 9.7950mm, 50%: 10.7467mm, 75%: 13.2700 mm,...
