 Evergreen coniferous tree, up to 40m tall, native in Europe, widely planted as ornamental and for use as a Christmas tree.
-"A GC/MS analysis of the volatile constituents from the flowers of Norway Spruce, Picea abies, has been carried out. The volatile constituents of the female flowers were distinctly different from those of the male flowers and the twigs. Characteristic constituents are methyl and ethyl benzoate, methyl and ethyl salicylate, methyl and ethyl butanoate, borneol and bornyl acetate. In the scent from the male flowers we could only detect the same monoterpenes as in the twigs."
+Myrcene, limonene, β-phellandrene, and methyl salicylate were the main volatile components extracted by SPME (Tenax) from the flower scent of Norway Spruce. "The volatile constituents of the female flowers were distinctly different from those of the male flowers and the twigs.
