Chemische Eigenschaften
Anise oil or Aniseed oil is obtained by steam distillation of the fruits of
Pimpinella anisum L. (Apiaceae). It is a colorless to pale yellow liquid or
crystalline mass with a powerful, sweet odor, characteristic of anethole.

Themain component of anise oil is (E)-anethole, which is present at a concentration
of 87–94% and which determines themelting point of the oil.
The oil has now been replaced, to a large extent, by the less expensive star anise oil, which also contains high percentages of anethole, but is still produced, for
example, in Hungary and Egypt on a small scale.
Anise oil is used for flavoring foods, beverages, and oral care products.
Physikalische Eigenschaften
Anise oil is a colorless to pale-yellow, strongly refractive liquid.
Essential oil composition
The seeds yield 2.5% of the oil on steam distillation. The major components of the oil are typically
95% trans-anethole (strong, sweet, anise) and 2% methyl chavicol (strong, sweet, tarragon). TNO (2000) reported presence of 44
compounds in anise. Of these, 23 were hydrocarbons, 8 phenols, 4 alcohols, 3 carbonyl ketones, 1 carbonyl aldehyde, 1 acid and 4
unknown compounds.
