The chemical composition and the antibacterial effect of the essential oils of Citrus paradisi, Juglans neotropica Diels, Schinus molle L. and Tagetes elliptica Smith) were determinided for gas chromatography/Mass spectrometry (GC/MS) and plate microdilution respectively were studied. In Citrus paradisi, 21 components were found, the main ones being D-Limonene (83,45%), octanal (8,68%) and β-myrcene (2,48%); in Juglans neotropica Diels 36 components were found, the main ones being α-pinene (39,88%), caryophylene (27,66%) and β-pinene (11,00%); 37 components were found in Schinus molle, the main α-phelandrene (19,59%), camphene (19,10%) and α-pinene (16,56%); and in Tagetes elliptica Smith found 33 components, with the majority being β-mircene (63,49%), cis-lanalool oxide (10,07%) and 2-tujene (7,77%). The minimum inhibitory concentration (MIC) for the essential oils of Citrus paradisi, Juglans neotropica Diels, Schinus molle L. and Tagetes elliptica Smith were less than 2.5 µL/mL for Staphylococcus aureus, and for Staphylococcus epidermidis were less than 5 µL/mL, with the exception of Juglans neotropica Diels which was > 40 µL/mL; and all the oils were inactive against Pseudomonas aeruginosa. The results found corroborate the great antibacterial potential of the essential oils studied. [ABSTRACT FROM AUTHOR]
La composición química y el efecto antibacteriano de los aceites esenciales de Citrus paradisi, Juglans neotropica Diels, Schinus molle L. y Tagetes elliptica Smith) fueron determinados por cromatografía de gases/espectrometría de masas (CG/EM) y microdilución en placa respectivamente. En Citrus paradisi, se encontraron 21 componentes, siendo los principales el D-Limoneno (83,45%), octanal (8,68%) y β-mirceno (2,48%); en Juglans neotropica Diels se encontraron 36 componentes, siendo los principales el α-pineno (39,88%), cariofileno (27,66%) y β-pineno (11,00%); en Schinus molle se encontraron 37 componentes, siendo los principales α-felandreno (19,59%), canfeno (19,10%) y α--pineno (16,56%); y en Tagetes elliptica Smith se encontraron 33 componentes, siendo los mayoritarios β-mirceno (63,49%), cis-lanalool óxido (10,07%) y 2-tujeno (7,77%). Las concentraciones mínimas inhibitorias (CMIs) para los aceites esenciales de Citrus paradisi, Juglans neotropica Diels, Schinus molle L. y Tagetes elliptica Smith fueron menores a 2,5 µL/mL para Staphylococcus aureus, y para Staphylococcus epidermidis fueron menores de 5 µL/mL, con excepción de Juglans neotropica Diels que fue > 40 µL/mL; y todos los aceites fueron inactivos contra Pseudomonas aeruginosa. Los resultados encontrados corroboran el gran potencial antibacteriano de los aceites esenciales estudiados. [ABSTRACT FROM AUTHOR]
