Comparative Study of Hydroethanolic and Aqueous Extracts of Two Medicinal Plants from Côte d’Ivoire

In order to highlight the antibacterial potential of the barks of Bauhinia thonningii and Cnestis ferruginea from the Ivorian flora, a new phytochemical and antibacterial investigation was conducted on their hydroethanolic extracts against multidrug-resistant strains of Pseudomonas aeruginosa and Acinetobacter baumannii. However, these extracts were also found to be ineffective. Nevertheless, the phytochemical screening identified polyphenols, flavonoids, tannins, coumarins, alkaloids, and terpenes. Quantification showed that the concentrations of these compounds in the hydroethanolic extracts of the plant species were relatively lower than in the aqueous extracts. However, the identification of these chemical compound groups could justify the use of these plant species in the traditional treatment of certain diseases. Keywords: Bauhinia thonningii, Cnestis ferruginea, Pseudomonas aeruginosa, Acinetobacter baumannii
