          Abstract

          Con ayuda de la cromatografía gaseosa capilar, espectrometría de masas y espectroscopia infrarroja, se estudiaron los componentes volátiles del aceite esencial de Lippia alba (Mill.) N. E. Br., lográndose identificar 43 compuestos, de los cuales 20 se informan por primera vez. Se encontró un alto contenido de carvona que hace suponer que se está en presencia de un nuevo quimiotipo. Se evaluó la actividad antibacteriana del aceite esencial sobre una bacteria integrada por 9 especies de bacterias, mediante la determinación de las concentraciones mínimas inhibitorias y con el empleo del método de las diluciones seriadas dobles en medio líquido. El aceite presentó actividad antibacteriana, siendo mayor en general, sobre los gérmenes grampositivos, con valores de las concentraciones mínimas inhibitorias entre 0,3 y 0,63 mg/mL.

          With the aid of capillary gas chromatography, mass spectrometry, and infrared spectroscopy, the volatile components of Lippia alba (Mill.) N.E. Br. essential oil, were studied, achieving the identification of 43 compounds, 20 of them reported for the first time. A high contents of carvone (carvona) was found, and this suggests the presence of a new chemotype. The antibacterial activity of the essential oil on a bacteria integrated by 9 bacterial species, was valuated by determining the inhibitory minimal concentrations, and with the use of the method of double dilution series in a liquid medium. The oil presented antibacterial activity, generally being higher on gram-positive germs, with values of the inhibitory minimal concentrations between 0,3 and 0,63 mg/L.
