ANTIMICROBIAL ACTIVITY OF ESSENTIAL OIL OF PISTACIA LENTISCUS GROWING IN FOREST OF BOUMERDES

Pistacia lentiscus L. family (Anacardiaceae) is an evergreen shrub native to the Mediterranean region and Middle East. The leaves of P. lentiscus (mastic tree) P. lentiscus samples were collected in October in a forest ecosystem of northeastern Algiers (Khemis El Khechna). The leaves were air dried in a shadowy place, then ground into powder. The essential oil from the leaves of Pistacia lentiscus grown in Algeria was obtained by the hydrodistillation method, separating the components of the extracts was performed by the method of thin layer chromatography. We conducted microbiological tests on gram-positive and gram-negative bacteria, on fungi and yeasts. His action is more important yeast Candida albicans and Aspergillus niger mold whose growth was strongly inhibited in comparison with bacterial strains.
