Syzygium  plants are known as sources of biologically active substances. The essential oils constituents and antimicrobial activity of  Syzygium petelotii  Merr. &amp; Perry and  Syzygium syzygioides  (Miq.) Merr. &amp; Perry from Vietnam are being reported. Essential oils were obtained by hydrodistillation of the leaves of  S. petelotii  and  S. syzygioides  collected from Pù Hoạt Nature Reserve, Vietnam. The constituents of the essential oils were determined by using gas chromatography (GC) and gas chromatography-mass (GC/MS) spectrometry methods. The antimicrobial activity was evaluated by microdilution broth susceptibility assay. The results indicate that γ-guaiene (24.1%), β-caryphyllene (9.3%), α-pinene (7.8%), and β-pinene (6.1%) were the major compounds of  S. petelotii . The main constituents of  S. syzygioides  were caryophyllene oxide (14.8%), α-pinene (10.6%), β-pinene (6.6%) and spathulenol (6.4%). The essential oil of  S. petelotii  showed pronounced antimicrobial activity against  Pseudomonas aeruginosa  ATCC27853 and  Enterococcus faecalis  ATCC299212, with minimum inhibitory concentration (MIC) values of 16.0 μg/mL and 64.0 μg/mL, respectively. The essential oil of  S. syzygioides  only displayed activity towards  Pseudomonas aeruginosa  ATCC27853 with MIC value of 32.0 μg/mL. Both essential oils exhibited antimicrobial activity towards  Bacillus cereus  ATCC14579 (MIC value, 128.0 μg/mL), and anti-candidal action against  Candida albicans  ATCC10231 with MIC value of 64.0 μg/mL. The chemical compositions and antimicrobial activity of essential oils of  S. petelotii  and  S. syzygioides  are being reported for the first time.
