Antibacterial Activity Of Extracts Of Piper Guineense On Some Common Pathogens
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.
