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 Pistacialentiscusas a medicinal herb. For their antimicrobial activity, extracts of tannin and polyphenols werescreenedagainst 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.enPistacialentiscus; leaves;phytochemistry;biological activity.Article
