PHYTOCHEMICAL STUDY AND IN VITRO ANTIMICROBIAL ACTIVITY OF PISTACIA LENTISCUS L. IN BOUMERDES MOUNTAINOUS REGION (ALGERIA)

<p><em>Pistacia lentiscus</em> L. (Pistaciaceae) is among the most important medicinal plants in Algeria that is known for its antifungal and antimicrobial properties. For this study, the leaves were collected from the mountainous region of Boumerdes, in northern Algeria. In such a propitious context, the aim of this study was to enhance <em>Pistacia lentiscus</em> as a medicinal herb. For their antimicrobial activity, extracts of tannin and polyphenols were screened against three pathogenic bacterial strains and one pathogenic yeast strains. The phytochemical analysis results showed a remarkable combination of chemical components including a high content in tannins, in leucoanthocyanins, in glucosids, alcaloids, flavonoïds and in saponosids. The tannins and the polyphenols have strong antimicrobial activity against some species.
