The needle-terpene profiles of two natural Pinus peuce populations from
the Scardo-Pindic mountain system (Mt. Osljak and Mt. Pelister) were
analyzed. Among the 90 detected compounds, 87 were identified. The
dominant constituents were alpha-pinene (45.5\%), germacrene D (11.1\%),
beta-pinene (10.8\%), and camphene (10.3\%). The following eight
additional components were found to be present in medium-to-high amounts
(0.5-10\%): bornyl acetate (5.0\%), beta-phellandrene (3.4\%),
beta-caryophyllene (2.9\%), beta-myrcene (0.9\%), germacrene D-4-ol
(0.9\%), tricyclene (0.7\%), (E)-hex-2-enal (0.7\%), and
bicyclogermacrene (0.6\%). Although the general needle-terpene profiles
of the populations from Mt. Osljak and Mt. Pelister were found to be
similar to those of the populations from Zeletin, Sjekirica, and Mokra
Gora (Dinaric Alps), principle component analysis (PCA) of eight
terpenes (alpha-pinene, beta-myrcene, alpha-terpinolene, bornyl acetate,
alpha-terpinyl acetate, beta-caryophyllene, trans-beta-farnesene, and
germacrene D) in 139 tree samples suggested a divergence between the two
population groups, i.e., the samples from the Scardo-Pindic mountain
system and those from the Dinaric Alps. Genetic analysis of the
beta-pinene content demonstrated a partial divergence between the two
geographical groups. The profiles of both population groups differed
from those published for populations from the Balkan-Rhodope mountains
system (literature results), which were characterized by high contents
of bornyl acetate and citronellol (Greek populations) or delta-car-3-ene
(Bulgarian populations).
