The slightly turpentine-like odor and the relatively low solubility of the oil
are caused by its high content of α-pinene (25–45%) and other monoterpene
hydrocarbons. The main oxygen-containing component is 1-terpinen-4-ol (1–6%) .
In Europe, for example, in Hungary and Bulgaria, juniper berry oil is distilled
from berries growing in the traditional Balkan regions such as Macedonia. A different
quality of juniper berry oil is distilled in India. The production quantity
amounts to ～10 t annually.
A so-called juniper leaf oil is obtained fromthe twigs of the juniper bush, which
contain wood, needles, and berries. Its sensory properties are completely different
in terms of being more turpentine-like.
The oil is used to a limited extent in perfumery for creating fresh, dry effects
and as an aroma ingredient in alcoholic beverages of the gin type.
