The antibacterial effect of the sagebrush essential oil (Artemisia herba-alba Asso.) of Western Algeria

摘要

The essential oil of sagebrush (Artemisia herba-alba Asso.) of western Algeria is subject to a physico-chemical and microbiological study. The extraction of the essential oil was carried out by hydrodistillation using a Clevenger-type apparatus. The yield obtained from the aerial parts of this plant is interesting for industrial exploitation. Analyses of the sagebrush essential oil were carried out to determine the physical and chemical indices. The study of the essential oil activity on the bacterial strains (Escherichia coli, Bacillus subtilis, Staphylococcus aureus) by the technique of Vincent (aromatogram) showed that all of the tested bacterial strains were highly sensitive.
