Abstract

The aim of this study was to identify the groups of chemical compounds present in the aqueous extract of B. thoninginii bark from Ivorian flora and to assess its antibacterial activity against multi-resistant strains of P. aeruginosa and A. baumannii. Phytochemical sorting was used to identify polyphenols, flavonoids, tannins, coumarins, alkaloids, terpenes and derivatives. The levels of polyphenols, flavonoids, flavone aglycones, anthocyanins and condensed tannins were respectively 0.748 ± 0.03, 0.091 ± 0.01, 0.0094 ± 0.03, 0.0359 ± 0.01 and 0.117 ± 0.02 mg EAG /g MS. Sensitivity tests showed that BT was ineffective against multi-resistant strains of P. aeruginosa and A. baumannii.
