This paper described the chemical compositions and antimicrobial activity of the essential oils from the leaves and stem of Amomum rubidumLamxay & N. S. Lý, collected from Bidoup Nui Ba National Park, Lam Dong, Vietnam. The essential oils were obtained by hydrodisitllation method while antimicrobial activity was evaluetd by microdilution broth susceptibility assay. The main constituents of the leaf essential oil were identified as 1,8-cineole (37.7%), -3-carene (19.5%) and limonene (16.3%) while -3-carene (21.9%), limonene (17.8%) and β-phellandrene (14.6%) dominated in the stem essentialoil. The leaf and stem essential oils displayed stronger inhibition of Pseudomonas aeruginosawith MIC of 25 μg/mLand 50 μg/mLrespectively. The stem essential oil was active against Candida albicans(MIC, 50 μg/mL) while both essential oils inhibited the growth of Fusarium oxysporum(MIC 50 μg/mL). This is the first report on chemical constituents and antimicrobial activity of the essential oils of A. rubidum.
