Abstract The chemical composition of the essential oil obtained from the oleo-gum resin of Commiphora myrrha (Nees) Engl. var. molmol was examined by using GC and GC/MS. Among the 32 components identified in this oil, curzerene (40.1%), furanoeudesma-1,3-diene (15.0%), Î²-elemene (8.4%) and 2-0-acetyl-8,12-epoxygermacra-1(10),4,7,11-tetraene, isomer I (6.5%) were found to be the major constituents.
