An In Vitro Study Of The Antimicrobial Activity Of The Root Extract Of Calotropis Procera And Moringa Oleifera

Abstract

The crude root extract of Moringa oleifera and Calotropis procera were investigated for antimicrobial activity on three organisms; Neisseria gonorrhoeae, Staphylococcus aureus and Escherichia coli. The disc plate diffusion method was used to determine the sensitivity of these organisms. Various concentrations of aqueous and 1% potash extract at 60%, 50%, and 40% were used. Extract from the root of Calotropis procera presented better inhibitory effect on the test organisms. Neisseria gonorrhoeae appeared most susceptible to the antimicrobial effect of the root extracts. Evidence of antimicrobial activities of the plants extracts underscores their therapeutic utilization traditionally.
