This study was designed to examine the chemical composition of essential oil and in vitro antioxidant antimicrobial activity methanol extracts Eucalyptus largiflorens F. Muell. The hydrodistilled leaves E. analyzed by gas chromatography chromatography/mass spectrometry. main constituents were found be 1,8-cineole (23.1%), cryptone (15.1%), 4-allyloxyimino-2-carene (11.2%), 4-terpineol (9.6%). showed strong antibacterial against studied microorganisms, except for P. aeruginosa, while polar subfraction extract had moderate nonpolar did not show any activity. In contrast, better than assays employed, e.g., a 2,2-diphenyl-1-picryl-hydrazyl system. Also, (15.1 ± 0.7 μg/ml) highest radical-scavenging second case, inhibition capacity (%) (92.7% 2.5) stronger one. Finally, total amounts phenol (142.6 0.9 μg/mg), (68.6 0.4 (36.0 0.6 μg/mg) determined.
