ABSTRACT
This research was focus on the extraction and antimicrobial screening of essential oil obtained from some medicinal plants. The antimicrobial screening of the various essential oils were carried out using micro broth dilution technique The result of the antimicrobial activities ofmethanolic extract of the stem-bark/leaves of the plants revealed that Bosweilliadalzielii, Ocimumamericanus, Hyptisspicigera, Hyptissuaveolens, Eucalyptus cammaldulensis, vossiacuspidata, Lavandulaofficinalis, Cinnamondedronecubenes, D. microcarpun, D. Mespilisformis, Isoberliniadoka, L. korstringi, and K. sengalensis have actitivtiesagains microorganisms.. The result shows that the essential oil of Ocimumamericanus has wide spectrum antimicrobial activity whereas the other essential oils exhibited selective antimicrobial activities.
