Determinación del efecto antibacteriano de aceites esenciales obtenidos de la familia Myracaceae y Lamiceae

Abstract

Science has real interest in the use of natural substances for microbial control is one of the areas that is booming today, between plants are those that produce essential oils. In this study the antibacterial activity of essential oils extracted from Clinopodiumtenellum( Huarmi Pennyroyal ) , Morella Parvifolia ( Laurel wax ) on strains of S. aureus ATCC 25923 and E. coli ATCC 25922, causing infectious diseases as sought : gastrointestinal and respiratory , respectively.

From Clinopodiumtenellum , Morella Parvifolia , essential oils are obtained by distillation by steam with a Clevenger trap . Which were analyzed by gas chromatography using the following five patterns ( alpha-pinene, beta -pinene , linalool , limonene and menthone ) .

For microbiological analysis, a screening was performed using the microdilutionplate , with which it is possible to determine the minimum inhibitory concentration (MIC ) in which the activity or negativity is based antimicrobial effect . The essential oils and Morella ParvifoliaClinopodiumtenellum were analyzed at different concentrations. The study demonstrated for the essential oil of Clinopodiumtenellum mild activity at a concentration of 867.8 mg / ml ( MIC 50 ) for E. coli and no activity on S. aureus , and the essential oil of Morella Parvifolia no activity on E. coli and S. aureus.
