Chemische Eigenschaften
Fennel oil is obtained by steam distillation of the aerial parts of Foeniculum

The main constituents are monoterpene hydrocarbons such as ??-phellandrene
(0–8.5%) and limonene (1–6%), fenchone (10–25%), estragole (1–6%), and
(E)-anethole (50–78%). With increasing maturity of the fruits, the content
of monoterpenes decreases. The ripe fruits yield an oil with 50–70% anethole and
5–25% fenchone. In contrast, the oil of the ripe fruits of sweet fennel (F. vulgare
Mill. ssp. vulgare var. dulce) contains less than 5% fenchone and more than 75% anethole.
Fennel oil is produced mainly in Hungary, Tasmania, North Africa, and India
in a quantity of few 10 t/yr. In total. It is used in flavoring oral care products and
alcoholic beverages (anise liqueurs).
