With a view to enhancing the many plant species that make up the Ivorian flora, a study on the medicinal properties of two plants, Boerhavia diffusa and Kaya senegalensis, was carried out with the main objective of evaluating their antibacterial activities. Sensitivity tests carried out (MIC and MBC) on two bacterial strains (Escherichia coli and Staphylococcus aureus) revealed that the aqueous extract of Boerhavia diffusa has bactericidal activity against E. coli and bacteriostatic activity against S. aureus that of Khaya senegalensis is bactericidal against S. aureus but without any activity against E. coli up to the limit of 800 mg/mL of concentration tested. The antibacterial activities of these plants would be due to the active ingredients it contains, in particular sterols and polyterpenes (polyphenols, tannins, saponosides) but the advantage observed in Boerhavia diffusa would be due to the flavonoids it contains.

Abstract: (french)
Dans la perspective de valoriser les nombreuses espèces végétales qui composent la flore ivoirienne, une étude portant sur les vertus médicinales de deux plantes, Boerhavia diffusa et Kaya senegalensis, a été réalisée avec pour principal objectif l’évaluation des activités antibactériennes. Des tests de sensibilité réalisés (CMI et CMB) sur deux souches bactériennes (E. coli et S. aureus) ont permis de révéler que l’extrait aqueux de Boerhavia diffusa présente une activité bactéricide contre E. coli et bactériostatique contre S. aureus alors que celui de Khaya senegalensis est bactéricide contre S. aureus mais sans aucune activité contre E coli jusqu’à la limite de 800 mg/mL de concentration expérimentée. Les activités antibactériennes de ces plantes seraient dues aux principes actifs qu’elle renferme notamment les stérols et polyterpènes (polyphénols, tanins, saponosides) mais l’avantage constaté chez Boerhavia diffusa serait dû aux flavonïdes qu’elle renferme.
