Antimicrobial activities of the leaf oils obtained were also evaluated. Ninety-three compounds were identified in the hydrodistilled leaf oil, and 74 compounds were identified by the headspace-GC and GC/MS method, respectively. The main components of the oils were β-caryophyllene (10.5%), β-phellandrene (7.8%), τ-muurolol (5.3%), α-phellandrene (5.1%) and δ-cadinene (5.0%). The leaf oils exhibited excellent antimicrobial activities.
