Caracterización y determinación de la actividad antimicrobiana de aceites esenciales de las familias (verbenaceae, lamiaceae, rutaceae, myrtaceae, apiaceae y poaceae), frente a enterobacterias y candida albicans

Abstract

Ten essential oils were obtained of different plant materials of Pimpinella anisum (anise - seed), Citrus sinensis (orange - peel), Aloysia citriodora (cidrón), Ruta graveolens (ruda), Mentha pulegium (pennyroyal), Citrus reticulata (mandarin - peel), Foeniculum vulgare (fennel), Cymbopogon citratus (limonaria), Eucalyptus globulus (eucalyptus) and Romarinus officinalis (rosemary) using the microwave-assisted hydrodistillation method, with yielding between 1.5% and 0.007%. The antimicrobial activity of the essential oils was evaluated by means of the plate microdilution method against the microorganisms Escherichia coli, Salmonella typhi and Candida albicans, resulting in that the AE of limonaria was the one that presented the best activity against E. coli (MIC: 2000-1000 μg / mL, CBM: 2000-1000 μg / mL) and against C. albicans (MIC: 500-250 μg / mL, CFM: 500-250 μg / mL). Additionally, the cytotoxicity of the oils was evaluated, of which the eucalyptus oil was one of the least cytotoxicity with CC50> 3000μg / mL against Vero and J774 cells.
