ABIES ALBA LEAF OIL Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Pyramidal, tall evergreen trees having horizontal branches, linear perennial leaves, and scaly cones. The parts used are the needles, twigs, and cones. Fir, pine has a very pleasant, balsamic, fresh odor and a bitter, pungent flavor.
A. sibirica, or Siberian fir, grows in the northern part of the former Soviet Union, Finland, and North America.
A. alba, silver fir or European fir, grows extensively in Europe (Germany, Austria, Switzerland and the former Yugoslavia). The tree has a characteristic whitish bark.
A. mayriana, or Japanese fir, grows specifically in Japan (Hokkaido Island).
Oils, distilled from Picea and Pinus species, are often traded under the generic name of fir needles oils.
A. alba (or A. excelsa or A. picea) essential oil is obtained by steam distillation of needles and twigs of European fir in approximately 0.3% yields. The oil is a colorless to pale-yellow liquid with a pleasant, balsamic odor of fir needles and a bitter, pungent flavor. Its main constituents include ι-α-pinene, ι-limonene, ι- bornyl acetate, lauric and decyclic aldehydes, and probably a sesquiterpene.
An essential oil is water- or steam-distilled also from the crushed cones of A. alba (Austria, (former) Yugoslavia, Switzerland, Germany). This so-called templin oil is a colorless to pale-yellow liquid with a fresh, balsamic odor somewhat reminiscent of petit- grain oil. Its physical-chemical constants vary depending on the source.
The composition of fir cones essential oil is very similar to the oil distilled from needles and twigs. It is usually added in small amounts to fir needles essential oil.
Chemische Eigenschaften
European silver fir oil is produced in Central or (South) Eastern
Europe by steamdistillation of needle-bearing twigs of Abies alba Mill. It is a
colorless to pale yellow liquid with a pleasant odor of freshly cut fir needles.

Silver fir cone oil (templin oil) obtained from the cones of A. alba Mill.,
has similar properties.
Physikalische Eigenschaften
Oil from A alba needles, twigs and other crushed cones is a colorless to pale-yellow liquid.
Sicherheitsprofil
Low toxicity by ingestion or skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
