Melaleuca alternifolia Cheel was acclimatized from Australia to grow in Vietnam. Samples were collected from various provinces, and the analysis of M. alternifolia Cheel was performed by means of gas chromatography-mass spectrometry to afford four different chemotypes with terpinene-4-ol (34.08-40.44%), terpinelene (39.47-60.34%), 1,8-cineole (71.23-77.54%) and terpinolene (34.89-38.30%) plus 1,8-cineole (30.84-35.26%) respectively as main components of the essential oil
