ABSTRACT

 Aqueous (cold and hot water) and ethanol extracts of Piper guineense seeds were screened for antibacterial activity against four microbes, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and Staphylococcus aureus. The aqueous extract of this plant showed minimal level of inhibition on E.coli and S.aureus at the highest concentration (2000µg/ml),with no effect at all on P.aeruginosa and S. typhi. The ethanol extract exhibited more inhibitory effect on Staphylococcus aureus, E. coli, and Salmonella typhi with no effect on Pseudomonas aeruginosa.  The minimum inhibitory concentration of the aqueous extract (cold and hot water extract) was at 500µg/ml, while that of ethanol was at 62.5µg/ml. The qualitative determination of chemical constituent of the plant confirmed the presence of certain metabolites such as Alkoloids, Saponins, Tannins, Oleoresin and Glycosides. The results obtained show that the extract of Piper guineense possess some level of antibacterial activity against some common pathogens.
