Analysis of Juniperus communis subsp. alpina needle, berry, wood and root oils ...
Description
The essential oils from needles, berries, wood and roots of Juniperus communis L. subsp. alpina were obtained by hydrodistillation, fractionated on column chromatography and analysed by GC, GC-MS and 13C-NMR. Chemical compositions of wood and root oils are reported here for the first time. Eighty-two, 65, 76 and 54 components were identified, respectively, in needle, berry, wood and root oils. The chemical compositions of the essential oils from needles, berries and wood were characterized by a high proportion of monoterpene hydrocarbons. Root oil exhibited a quite different composition. Sesquiterpenes, especially those bearing a tricyclic skeleton (cedrane and longifolane), constituted the main fraction while monoterpenes were present at very low contents.
