Analysis of Volatile Constituents from Commiphora myrrha Engl. of Xinjiang by Gas Chromatography-Mass Spectrometry

The essential oil in the Commiphora myrrha Engl. was extracted by steam distillation method, and the chemical constituents of the volatile from the herb were identified by gas chromatography-mass spectrometry (GC/MS). Forty-two compounds were identified, which accounted for over 87.46 % of the volatile oil. The major components were α-bergamotene(12.52 %), β-selinene (8.75%), β-bisabolene (10.03%), 2-hydroxy-2,4,6-cycloheptatrien-1-one(6.25%), and so on.
