Abstract: Dracaena braunii, (is also known as Lucky Bamboo), is named after the German-English gardener Henry Frederick Conrad Sander (1847-1920) which belongs to family Asparagaceae. It is distributed in tropical and subtropical open lands of India and Africa. The genus Dracaena is well known as indoor ornamental plants. Some of the Dracaena species possess several medicinal properties and are used in curing a number of diseases. Dracaena braunii is also used for various ailments by traditional healers in other parts of the world. This study is carried out to evaluate the in vitro antimicrobial activity and to determine the most effective solvent for extraction of Dracaena braunii. This study utilized the experimental method of research and evaluated the antimicrobial property of Dracaene braunii leaf. The Dracaena leaf extract was prepared by mixing pulverized leaf materials using methanol and ethanol. The test organism used in the said study were Escherichia coli and Staphylococcus aureus, with a positive control of Amoxicillin, Tetracycline and Chloramphenicol. The zone of inhibition was measured in millimeter (mm). The result of this study supports antibacterial property of Dracaena braunii leaf against Escherichia coli and Staphylococcus aureus. It can be concluded that using in vitro experiments established that the extract Dracaena braunii inhibited bacterial growth in oth methods and different solvent extracts. Such results varied in ethanolic extract, where the size of inhibition exhibits more than methanolic extract. Therefore, the results showed that Staphylococcus aureus is more susceptible than Escherichia coli in antimicrobial of this plant crude extracts.
