The needle-terpene profiles of two natural Pinus heldreichii populations
from Mts. Oljak and Galiica (Scardo-Pindic mountain system) were
analyzed. Among the 68 detected compounds, 66 were identified. The
dominant constituents were germacrene D (28.7\%), limonene (27.1\%), and
-pinene (16.2\%). -Caryophyllene (6.9\%), -pinene (5.2\%), -myrcene
(2.3\%), pimaric acid (2.0\%), -humulene (1.2\%), and seven additional
components were found to be present in medium-to-high amounts
(0.5-10\%). Although the general needle-terpene profile of the
population from Galiica was similar to those of the populations from
Loven, Zeletin, Bjelasica, and Zlatibor-Peter (belonging to the Dinaric
Alps), the principle-component analysis (PCA) of seven terpenes
(-myrcene, limonene, -elemene, -caryophyllene, -humulene, -cadinene, and
germacrene D-4-ol) in 121 tree samples suggested a partial divergence in
the needle-terpene profiles between the populations from the
Scardo-Pindic mountain system and the Dinaric Alps. According to
previously reported data, the P. heldreichii samples from the
Balkan-Rhodope mountains lack -caryophyllene and germacrene D, but
contain -muurolene in their terpene profile. Differences in the terpene
composition between populations growing in the three above-mentioned
mountain systems were compared and discussed.
