The present work aimed to evaluate the antimicrobial potential of <i>Lippia origanoides</i> Kunth against two bacteria strains: <i>Escherichia coli</i> and <i>Staphylococcus aureus</i>. Leaf essential oils were obtained by hydrodistillation in a modified Clevenger-type apparatus, and their chemical composition was determined by gas chromatography coupled to mass spectrometry (GC/MS) and flame ionization detection (GC/FID). We identified 28 compounds, representing 98.87% of the total concentration of the essential oil. The compounds identified at the highest concentrations were 1,8-cineole (35.04%), carvacrol (11.32%), p-cymene (8.53%), <Evidence-based complementary and alternative medicine : eCAMChemical Composition and Antibacterial Activity of the <i>Lippia origanoides</i> Kunth Essential Oil from the Carajas National Forest, Brazil.PMC8548111302050/2021-3Moacir do Rosario Marinho Ade Aguiar Andrade EHFavacho Ribeiro ASantana Barbosa Marinho PRibeiro FPde Oliveira Feitosa ASantana de Oliveira MfalseChemical Composition and Antibacterial Activity of the <i>Lippia origanoides</i> Kunth Essential Oil from the Carajas National Forest, Brazil.Species of the genus <i>Lippia</i> are rich in essential oils and have shown antibacterial properties, which may be related to oils' chemical composition.
