The discovery of a new species exhibiting more effective antibacterial properties is necessary because of the demand on species, which continues to increase in a variety of industries. might be a good alternative, as it exhibits strong antibacterial activity. In this study, the chemical composition of the essential oils from different organs (flowers, leaves, stems, and roots) of was identified using gas chromatography-mass spectrometry. Furthermore, the antimicrobial activities of different solvent extracts (methanol, ethanol, diethyl ether, hexane, and ethyl acetate) and different organ (flower, leaf, stem, and root) extracts of were evaluated. Only the ethyl acetate extracts of exhibited antibacterial activity against all bacterial strains tested, including , (KF 918342), (KCTC 12487), (ATCC 35150), (ATCC 29544), and (KACC 15136). In particular, the extracts exhibited significant activity against Ethyl acetate extract of the leaf exhibited the best activity against all bacterial strains. This study provides valuable information on the chemical compositions in essential oils and antimicrobial properties of .
