ResumoAccording to the popular medicine, the infusion Eugenia uniflora L., popularly known as Brazilian cherry, has antimicrobial, antidiarrheal, diuretic, antireumatic, antipyretic, reducing cholesterol and uric acid in the urine.With base of this data, the work aimed to perform the phytochemical characterization of oil and assess the antibacterial activity in vitro on strains of Enterobacter aerogenes and Salmonella typhimurium.The collection of Brazilian cherry leaves was held during the month of February 2015, in São Lourenço do Sul, Rio Grande do Sul, Brazil.The chromatographic conditions were: initial temperature of 50ºC, rising to 10ºC/min, until achieved 280ºC, remaining in this temperature for 10 min; injected volume of 1 µl; 300ºC interface; 280ºC of temperature injector; helium as carrier gas; linear gas flow of 1.20 mL.min -1; split of 1:50; running scan mode; mass strip of 40 at 700 m/z and 70eV filament voltage.To evaluate the antibacterial activity, we used the determination of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC).The phytochemical characterization allowed us to identify 12 compounds: trans-β-ocimene, cis-β-ocimene, caryophyllene, allo-aromadendrene, β-copaene, α-muurolene, (+)-δ-cadinene, spathulenol, viridiflorol, Isolongifolene, 9,10-dehydro-, α-epi-cadinol and cis-Dihydro-α-copaene-8ol.Oil yield obtained in the extraction process was 0.65% and inhibition action was found facing the strains of E. aerogenes and S.typhimurium with 3.125%.Thus, it can be concluded that the essential oil of Brazilian cherry is an alternative medical means with antibacterial action on E.aerogenes and S.typhimurium is considered possible natural source for the development of new drugs.
