ABSTRACT
The Antibacterial Activity Of The Ethanolic And Aqueous
Extracts Of Piper Guineense, Xylopia Aethiopica And Garcinia Kola Against
Eschericha Pseudomonas Aeruginosa And Staphylococcus Aureus Were
Evaluated Using The Impregnated Paper Disc And Agar-Well Diffusion Methods. The
Growth Inhibitory Response Varied With Bacterial Strains Tested And The Type Of
Extract. Ethanolic Extracts Of Garcinia Kola And Xylopia Aethiopica Produced A
Marked Inliibitoiy Effect On Staphycococcus Aureus And Pseudornonas Aeruginosa
(18.0mm — 21.0mm) And (17.0mm To 21.0mm) Respectively But Showed Little Or No
Activity Against Escherichia Coil. The Aqueous Extract Of Piper Guineense
Showed More Inhibitory Activity Than The Ethanol Extracts With Zone Diameter Of
24.0mm Against 14.4mm On Escherichia Coil, And 20.0mm Against 16.0mm On
Pseudomonas Aeruginosa. The Agar-Well Detennined Minimum Inhibitory
Concentration (Mic) Values For The Ethanolic And Aqueous Extracts Were Lower
Indicating Higher Sensitivity Than The Corresponding Paper Disc Determined
Values Probably Because Of Rapid Evaporation Of The Essential Oils From The
Paper Disc. The Mic Values Of The Three Plant Extracts Were In The Range Of
0.5mg (12.5mg/Mi) To 4mg (100mg/Mi). These Results Indicated That The Aqueous
And Ethanol Extracts Of These Plants Have Growth Inhibitory Effects In Vitro
Against Specific Bacteria Suggesting Their Use In Folk Medicine.
