The essential oil of Melaleuca cajuputi was obtained by hydrodistillation method. This work aims to adopt water as a solvent in a batchprocess to extract essential oil from Melaleuca cajuputi fresh leaves. The leaves are collected from Quang Tri Province, Vietnam. Analysisof constituents was performed by GC/MS. The maximum yield ranged from 0.6 to 0.7%. Several compounds have been identified in highquantities and meaningful qualitative and quantitative differences have been observed under different conditions. The main componentsof the M. cajuputi essential oil included eucalyptol (27.512%), γ-terpinene (8.59%), terpinolene (9.047%), β-eudesmene (3.359%), α-selinene (3.889%), α-terpineol (4.108%), 1R-α-pinene (2.158%), caryophyllene (6.48%) and α-caryophyllene (3.522%). This study hasconfirmed that the essential oil of M. cajuputi essential oil is a promising bactericidal agent on several Gram-positive and Gram-negativebacteria.
