Étude de l’activité antifongique des extraits d’Ocimum basilicum, Juniperus phoenecea et de Mentha spicata, sur les moisissures de la pourriture des fruits.

Abstract

The objective of this study is to use the essential oils of Ocimum basilicum, Juniperus phoenecea and Mentha spicata as biofungicides against fungal strains isolated and identified from rotten fruits. The different isolated species belong to the genera F. graminiarum, Pencellium sp and A. niger. The extraction method allowed us to obtain a yield, the highest of which is that of Ocimum basilicum (1.97%) followed by that of Juniperus phoenecea (1.2%) and followed by that of Mentha spicata (0.93%). The antifungal effect of each essential oil tested at two concentrations (1/400 and 1/2000) in an agar medium in Petri dishes, is estimated by determining the rate of inhibition of the growth of fungi. Indeed, the essential oil of Ocimum basilicum has a good antifungal effect; it totally inhibits the development of molds. Key words: antifungal, mold, essential oils, medicinal plants
