Abstract
The stem bark of Acacia albidawas extracted successively with hexane, chloroform, ethyl acetate and methanol. The antimicrobial activity of all extracts was investigated against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Aspergillusniger and Candia albicons. The methanol extract showed significant inhibition against all test organisms. The antioxidant activity of the methanol extract was evaluated using the2,2-diphenyl-1-picrylhydrazyl(DPPH) radical scavenging assay. The extract exhibited significant radical scavenging capacity.
