Geographic variation in the volatile leaf oils J. phoenicea var. phoenicea from throughout its range
Contributors
Description
The compositions of the volatile leaf oils from 5 populations from throughout the range of
Juniperus phoenicea
var.
phoenicea
were analyzed. Two chemotypes were found: normal leaf oils and
leaf oils containing cedarwood oil components. Except for the chemotypes (hi cedrol), the leaf oils of
J.
phoenicea
are high in
α
-pinene (41.2 - 51.9%) and manoyl oxide
(14.0 - 28.0%) with moderate amounts
of
α
-pinene, myrcene,
β
-phellandrene and (E)-caryophyllene. Li
ttle geographic variation was found in
the major components from Narbonne to Andorra, Zarago
za thence to El Peñón. The oil from the high
cedrol plants at Grazalema seems quite different due
to the presence of cedarwood oil components, but it
is actually not very different, if one removes the
heartwood terpenoids and re-normalizes the remaining
terpenoids. Trees with high cedarwood oil had 16.4
- 31.9% cedrol and moderate amounts of other
cedarwood oil components (eg.,
α
- &
β
-cedrene, 2-epi-funebrene, cis-thujopsene,
α
- &
β
-alaskene, (E)-
β
-
bisabolene, liguloxide, allo-cedrol).
