Polyphenol contents, in vitro antioxidant and antimicrobial activities of leaves and barks from of
Anogeissus leiocarpus, Khaya senegalensis, Sterculia setigera, Solanum incanum and Pterocarpus erinaceus
extracts obtained with aqueous acetone 80% (WAE) were investigated in this study. The present study was
conducted to evaluate the total phenolic contents, in vitro antioxidant and antibacterial properties.
Folin-ciocalteu and AlCl3 methods respectively were used for polyphenol content. The antioxidant potential
of the samples was evaluate using two separate methods, inhibition of free radical 2,2-diphenyl-1-
picrylhydrazyl (DPPH) and Iron (III) to iron (II) reduction activity (FRAP). In vitro antibacterial capacity of
aqueous acetone extracts were investigated by agar disc diffusion, micro-well dilution (MIC) and Minimum
Bactericidal Concentration (MBC) assay against five bacteria. Our extracts contained high levels of phenolics
and exhibited antibacterial activity against bacteria. S. aureus and B. cereus were the most sensitive; while
E. coli was the most resistant. There were highly positive relationships (R2 = 0.8454-0.9780) between phenolic
contents and antioxidant, activity antibacterial capacity and phenolic contents of the tested extracts against each
bacterium. This suggested that the antibacterial activity of the tested extracts was closely associated with their
phenolic constituents. In this study, the extract of Anogeissus leiocarpus leaves was presented the best results among all extracts.
