About 86–87% of total peak areas of chromatograms consist of monoterpenes and evaluating their composition in qualitative and quantitative manner they do not show significant differences with regard to varieties. Some increments of terpinen-4-ol, α—terpineol and α—terpinyl acetate was recognizable in the variety horizontalis, while the variety pyramidalis contained germacrene D and abietadiene to somewhat higher level. On the other side, a higher percentage of α—fenchene than that of camphene and the presence of a monoterpene hydrocarbon sylvestrene were found to bear some chemotaxonomic value for the taxon C. sempervirens.
