The composition and variability of the terpenes and their derivatives
isolated from the needles of a representative pool of 114 adult trees
originating from four natural populations of dwarf mountain pine (Pinus
mugoTurra) from the Julian Alps were investigated by GC-FID and GC/MS
analyses. In total, 54 of the 57 detected essential-oil components were
identified. Among the different compound classes present in the
essential oils, the chief constituents belonged to the monoterpenes,
comprising an average content of 79.67\% of the total oil composition
(74.80\% of monoterpene hydrocarbons and 4.87\% of oxygenated
monoterpenes). Sesquiterpenes were present in smaller amounts (average
content of 19.02\%), out of which 16.39\% were sesquiterpene
hydrocarbons and 2.62\% oxygenated sesquiterpenes. The most abundant
components in the needle essential oils were the monoterpenes
-car-3-ene, -phellandrene, -pinene, -myrcene, and -pinene and the
sesquiterpene -caryophyllene. From the total data set of 57 detected
compounds, 40 were selected for principal-component analysis (PCA),
discriminant analysis (DA), and cluster analysis (CA). The overlap
tendency of the four populations suggested by PCA, was as well observed
by DA. CA also demonstrated similarity among the populations, which was
the highest between Populations I and II.
