Étude du pouvoir antifongique de l’huile essentielle de cannelle
This study was undertaken to determinate the antifungal activity of essential oil from cinnamon bark. The essential oil was tested on fungal strains using three different techniques; the agar dilution test to determine the sensitivity for the strains, the microtitration method to determine the minimal inhibitory concentration (MIC) of the essential oil on the growth of yeasts, and finally a macrodilution test allowing the evaluation of the essential oil on the mycelial mass production of the fungal strains. The results obtained show that all the essential oil showed antifungal activity. The MICs were ranged from 1/640 to 1/2560 for the yeasts. For the moulds the MICs were ranged from 1/5000 to 1/10000. Evaluation of the effects of the mycelial production showed that the essential oil had the best antifungal effect. With a concentration of 0,05% the essential oil could totally inhibit the growth of all the species tested.
