Antibacterial Activity Of Extracts Of Piper Guineense On Some Common Pathogens:- Nwozuzu, Maureen O
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 (2000pg/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 500pg/ml, while that of ethanol was
at 62.5pg/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.
