Essential oils from the foliage of Picea sitchensis from British Columbia
AUTHOR(S): Alexis St-Gelais, Guy Collin, Johanna Helbig and Hélène Gagnon
ABSTRACT:Several essential oil samples of Picea sitchensis, Sitka spruce, needles were obtained from local producers in three different regions of British Columbia. They were analyzed by capillary GC and GC / MS techniques. These samples mainly contain monoterpenes (70 ± 10%) including Myrcene (12 - 33%) and b-phellandrene (16 - 35%). They also contain a variety of aliphatic and aromatic esters of saturated and unsaturated alcohols. It should be noted in particular the presence of isoamyl (0.8 - 6.4%) and 3-methyl-3-buten-1-yl (0 - 5.3%) isovalerates. These two esters make it possible to verify whether certain Sitka spruce populations have been "contaminated" byintrogression with white spruce populations. This seems to be the case for one of the samples collected in the Bella Coola Valley area, unlike those harvested in the Kitimaat area or on Graham Island.
