What does anethol mean?
Anethol is a naturally occurring organic compound responsible for the characteristic sweet, licorice-like aroma and taste of anise, fennel, and star anise. Chemically classified as an aromatic ether, it constitutes the major component of the essential oils distilled from these plants and is widely used as a flavouring agent in foods, confectionery, and alcoholic beverages such as ouzo, pastis, and absinthe, where it also contributes to the familiar cloudy 'louche' effect when the drink is diluted with water. Beyond flavouring, anethol finds application in perfumery and has been studied for potential biological activity. In scientific writing the compound is now more commonly referred to by the spelling 'anethole', making 'anethol' a term encountered mainly in older texts, trade documents, and ingredient listings.
nounAnethol is a fragrant organic compound (an aromatic ether) that is the principal component of the essential oils of anise and fennel, responsible for their characteristic sweet, licorice-like flavour and odour.
- A sweet-smelling crystalline organic compound, C10H12O, found in anise, fennel, and star anise oils, used as a flavouring agent and fragrance.
"The distinctive sweetness of ouzo comes largely from its high concentration of anethol."
"Star anise owes its warm, licorice-like aroma to its abundance of anethol."
"Commercially, anethol is extracted from fennel oil for use in confectionery and liqueurs."
Rarely used; the compound is typically discussed as a single substance rather than counted in plural form.
"Different distillation batches yielded slightly different proportions of anethols and related compounds."
That unmistakable licorice kick in absinthe, ouzo, and fennel tea? It's almost entirely one molecule: anethol.

Etymology of anethol
The name derives from 'anise' (Pimpinella anisum), whose essential oil was first recognised as the source of the compound; the suffix '-ol' reflects its classification as an alcohol-related organic compound in nineteenth-century chemical nomenclature. The word entered English through the conventions of organic chemistry naming, which frequently built compound names from the plant material they were isolated from. Related terms include estragole, a closely related anisole derivative found in tarragon and basil.
How anethol is actually used
Anethol is primarily encountered in chemistry, food science, and perfumery contexts rather than everyday conversation. The spelling 'anethol' appears chiefly in older or trade literature; contemporary scientific sources generally prefer 'anethole'.
Easily confused with anethol
Anethol is an older spelling variant of the same compound; modern chemistry literature uses 'anethole' as the standard name.
