化学的特性
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.
d2020 0.980-0.990; n20D 1.552-1.561;α20D ?2°to +2°; solubility: 1 vol in 3 vol of 90% ethanol at 20 ℃; fp 15–19.5℃.
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.

compounds in anise. Of these, 23 were hydrocarbons, 8 phenols, 4 alcohols, 3 carbonyl ketones, 1 carbonyl aldehyde, 1 acid and 4
