Etude physico chimique et évaluation de l’activité antibactérienne des huiles essentielles de la Sarriette des montagnes vis à vis des bactéries isolées des infections urinaires

Abstract

Essential oils have significant antimicrobial activities and can successfully

replace antibiotics that show their inefficiencies against resistant

microorganisms (Jonkers, 1999). The objective of this study is to develop the

use of essential oil of savory mountains to struggle against urinary tract

infections. The extraction is carried out by hydrodistillation. Analysis of essential

oils is performed by GC / MS. The antibacterial activity is highlighted by the

diffusion on agar medium method. The results showedthat the essential oil of

savory mountains is liquid pale yellow colored, having an aromatic odor, fresh

and camphor and chemotype carvacrol (20.85%). Moreover, aromatogram

indicates a very important activity of this essential oil on the growth of bacteria

isolated from urinary tract infection. The MIC obtained for all the strains tested

is that of the crude extract, with a value of 0.1 g/ l. In view of these results, the

essential oil of savory mountains seems to be appropriate to treat urinary tract

infections.
