Abstract

Hydroethanolic and aqueous extracts of leaf and stem bark of Parkia biglobosa check for this species in other resources (Jacq) Benth. (Mimosaceae) were tested against clinical isolates Escherichia coli check for this species in other resources , Salmonella typhi check for this species in other resources , Shigella dysenteriae check for this species in other resources and Enterococcus faecalis check for this species in other resources , and corresponding collection strains E. coli CIP 105 182, Salmonella enterica CIP 105 150, Shigella dysenteriae CIP 54-51 and Enterococcus faecalis CIP 103 907. Discs of Gentamicin, a broad spectrum antibiotic were used as positive controls.The results showed that all the extracts possess antimicrobial activities. A comparative study of the antibacterial activity of the leaves and that of the bark showed that for all the tested microorganisms, the hydroalcoholic extract of the bark is more active than the aqueous extract of the leaf. The hydroethanolic extract of the leaves is as effective as the aqueous extract of the stem bark prescribed by the traditional healer, suggesting it is possible to use leaves other than the roots and bark.The phytochemical screening showed that sterols and triterpenes, saponosides??, tannins, reducing compounds, coumarins, anthocyanosides, flavonosides are present in both bark and leaf but in different concentrations.
