Abstract


The stem oil of Calocedrus macrolepis Kurz collected from Ha Giang province, Vietnam, in May 2008 was isolated by steam distillation to give oil yield 0.15% and analyzed by Capillary GC and GC/MS. Thirty eight components have been identified accounting more than 78.7% of the oil respectively. The major constituents of this oil appeared to be benzoic acid (23.3%) and dodecan-7 ol (14.6%). Less predominant constituents included trimethylenehexane (7.3%), α-terpineol (6.6%), 1,3-cyclooctadiene (5.8%), 4-nitrostyrene (2.8%), undecane (2.7%), methyllenebornane (2.3%), tricyclene (2.3%), tricyclo (2.0%) and cavacrol methyl ther (1.1%). All the other components were in concentration of less than 0.1-0.9%.
