Abstract

The increased resistance of microorganisms to currently used antimicrobials and especially the high cost of synthetic molecules has directed research towards other substances likely to have antimicrobial activity. It is for this reason that this work aims to evaluate phenolic compounds and to study the antibacterial capacity of extracts of Anogeissus leiocarpus (DC.) Guill. and Perrot (Combretaceae) traditionally used for the management of avian salmonellosis in rural areas of Burkina Faso. For this purpose, we collected the bark of Anogeissus leiocarpus (DC.) Guill and Perrot (Combretaceae) in the commune of Dedougou. After extraction with acetone and water, colorimetric tests were performed on the different extracts obtained and revealed mostly the presence of tannins and coumarins. We found that the hydroacetone extract had an effective antibacterial activity compared to macerated extracts and aqueous decoctions. All the extracts had a power to inhibit the growth of different bacterial strains but this power was more important with the hydroacetone extract. This inhibition power is explained by the presence in important quantity of phenolic compounds. Among these extracts, the hydroacetone extract could be very relevant to prevent and treat salmonellosis of microbial origin in poultry.
