The present research work attempts to evaluate the antimicrobial activity of Ethanol and Methanol extracts of two traditional medicinal plants viz. Cinnamomum zeylanicum, Syzygium aromaticum. Since ethanol is the best solvent for dissolving the antimicrobial compound present as active phytoconstituents in plants, which extracted with ethanol. Each extract was tested for its antimicrobial activity against Eight most prevalent pathogenic microorganism Staphylococcus aureus, Salmonella typhi, Bacillus cereus, Bacillus subtilis, Escherichia coli, Enterobacter aerogenes, Micrococcus luteus, Aspergillus niger The preliminary antimicrobial activity testing was carried out by using agar well diffusion method and minimum inhibitory concentrations of the extract was then determined by using the micro broth dilution assay. All these plant extracts exhibited antimicrobial activity against tested microbes the ethanol & methanol extract of Cinnamomum zeylanicum showed the highest antimicrobial activity against Micrococcus luteus & Staphylococcus aureus with the zone of inhibition 16 mm.
