Abstract The essential oils obtained by steam distillation from the leaves and flowers of Colquhounia coccinea Wall. were analyzed by GC and GC/MS. flower A total of 96.8% and 93.7% of the constituents were identified in the leaf and oils, respectively. Both the oils were dominated by sesquiterpenoids. Î²-Caryophyllene (44.1â53.2%), germacrene D (7.0â15.8%), cadina-1â4-diene (11.1â12.4%), germacrene D-4-ol (1.8â12.2%), Î±-humulene (3.7â8.7%) and caryophyllene oxide (1.0â5.7%) were identified as the major constituents in both oils.
