Phytochemical analysis and antibacterial activity of extracts from the bark of Cnestis ferruginea (Vahl ex De Cantolle)

Abstract

This study aim is to highlight the antibacterial properties of the aqueous extract of Cnestis ferruginea bark from Ivorian flora against multidrug-resistant bacterial strains. Phytochemical composition, dosages, and antibacterial tests were performed to accomplish this. Thus, phytochemical screening showed polyphenols, flavonoids, tannins, coumarins, alkaloids, terpenes and derivatives. Quantitative phytochemical analyses showed the polyphenols flavonoids, flavonics aglycones, anthocyanins and tannins contents were 632±0.03; 9±0.01; 7±0.03±0.03; 12±0.01 and 135±0.02 μg/g respectively. The result of the in vitro study showed that C. ferruginea extract is ineffective against multidrug-resistant strains of P. aeruginosa and A. baumannii.
