Fresh leaves of C. laevigata collected from the same location in January (Jan), July (Jul) and December (Dec) 2010 were analyzed by GC/MS. The main compounds of the Jan sample were lae- vigatine (59.60%), germacrene-D (7.75%) and ?-sesquiphellandrene (6.56%), for the Jul oil laeviga- tine (62.61%), germacrene-D (7.37%), ?-sesquiphellandrene (6.67%) and ?-caryophyllene (5.39%), while Dec sample showed laevigatine (44.05%), ?-sesquiphellandrene (8.59%) and ?-caryophyllene (5.96%) as major components. Antibacterial assays showed activity against E.faecalis (1000 µg/mL), S. aureus (25 µg/mL) and S. aureus methicilline resistant (1000 µg/mL).
