Authors : Zineb Saadoune . Yacine Boutoumi .


The composition of the essential oils of Citrus sinensis (orange) and Citrus limonum (lemon) showed a microbiological activity. These essential oils were extracted by hydrodistillation from the peel of citrus fruit of Citrus sinensis and Citrus limonum. Their antibacterial activity was determined in vitro by two different methods (Aromatogram and Vapor phase methods) on 07 strains (04 bacteria, 02 yeasts and 01 fungus). The Screening highlighted that the two essential oils either pure or diluted had a remarkable bacteriostatic activity towards the growth of certain bacterial strain. Also, these two essential oils presented a strong power antifungal. It is clear from this study that the essential oil of Citrus limonum presented an antibacterial activity higher than the essential oil of Citrus sinensis against the same bacteria.
