Volatile constituents of Juniperus communis L., Taxus canadensis Marshall. and Tsuga canadensis (L.) Carr. from Canada
Abstract
The essential oil composition leaves of Juniperus communis L., Taxus canadensis Marshall. and Tsuga canadensis (L.)
Carr. from Canada were investigated by head space solid phase microextraction (HS-SPME) and gas chromatography/mass
spectrometry (GC-MS). Thirty-three, 30 and 31 components were identified representing 95.78%, 93.89%, 96.14% of the oil,
respectively. Limonene (26.12%), benzene (15.62%), -mrycene (9.08%) and -pinene (7.30%) were found to be the main
constituents of J. communis; 1-propanone (36.38%), morpholine (10.95%), methylamine (9.10%) and methanone (8.14%) were
detected main components of Taxus canadensis; bornylacetate (26.84%), -pinene (23.74%), camphene (11.93%) and limonene
(6.02%) were determined as major constituents of Tsuga canadensis. The chemical distributions of the essential oil compounds in the
genus pattern were discussed in means of chemotaxonomy and natural products
