ABSTRACT

This study is part of a goal to investigate chemical composition, antibacterial, antifungal and antioxidant activities of the flower buds extracts from the Algerian Polulus nigra L., which were collected from Djarifet - mansourah at Tlemcen city in the West Northern of Algeria. In organic extracts, tanins, flavonoïds, coumarins, alkaloids and terpenoïds were the principals secondary metabolites identified from the flower buds of black poplar. Antibacterial and antifungal activities of extracts were tested using agar-well diffusion method and micro-well determination of MIC assay against eleven bacteria and two Candida species. It was found that extracts of black poplar buds exhibit antibacterial and anticandidal activities with agar disk diffusion (7 to 43mm) and MIC methods (MIC= 90.33 µg/ml against several strains of bacteria and MIC=45.16 µg/ml against Candida albicans). The antioxidant effect of hydroalcoholic extract was evaluated using DPPH and FRAP assays. It was showed good and similar activity than ascorbic acid and BHA by DPPH method: IC50= 220µg/mL for hydroethanol extract.

KEYWORDS:

Populus nigra L. extracts, Antibacterial and antifungal activities, DPPH antioxidant power, Ferric reducing antioxidant power assay (FRAP).
