This study evaluated the chemical profile and antimicrobial activity of essential oil (EO) of P. dioica. The EOs were extracted by hydrodistillation and chemically characterized by gas chromatography coupled to mass spectrometry (GC/MS). The total phenolics were quantified by the Folin Ciocalteu method. For the antimicrobial assay, the Disc Diffusion and Broth Dilution method were applied to obtain the minimum inhibitory concentration and minimum bactericidal concentration. The main constituent of the EO was eugenol. The EO showed bactericidal activity against E. coli, S. aureus, P. aeruginosa, Salmonella sp., B. cereus, P. mirabilis, K. pneumoniae, S. sonnei, C. albicans, Fusarium sp., Penicillium sp. and Aspergilus sp. The results obtained are encouraged by the potential use of the EO studied in the control and combat of pathogenic microorganisms.

Los AE fueron extraídos por hidrodestilación y caracterizados químicamente por cromatografía de gases acoplados a espectrometría de masas (GC/MS). Los fenólicos totales fueron cuantificados por el método Folin-Ciocalteu. Para el ensayo antimicrobiano, se aplicó el método de difusión de discos y dilución de caldo para obtener la concentración inhibitoria mínima y la concentración bactericida mínima. El componente principal de la AE fue el eugenol. La AE mostró actividad bactericida contra E. coli, S. aureus, P. aeruginosa, Salmonella sp., B. cereus, P. mirabilis, K. pneumoniae, S. sonnei, C. albicans, Fusarium sp., Penicillium sp. y Aspergilus sp. Los resultados obtenidos son estimulados por el uso potencial de la AE estudiada en el control y combate de microorganismos patógenos.
