Eugenol / ˈ j uː dʒ ɪ n ɒ l / is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. [2] It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove , nutmeg , cinnamon , basil and bay leaf .
It is the methyl ether of eugenol and is important to insect behavior and pollination. [2] It is found in various essential oils. Methyl eugenol is found in a number of plants (over 450 species from 80 families including both angiosperm and gymnosperm families) and has a role in attracting pollinators. About 350 plant species have them as a ...
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Guaiacol is a precursor to various flavorants, such as eugenol. [15] An estimated 85% of the world's supply of vanillin comes from guaiacol. Because consumers tend to prefer natural vanillin to synthetic vanillin, methods such as microbial fermentation have been adopted.
The term "methyl" was derived in about 1840 by back-formation from "methylene", and was then applied to describe "methyl alcohol". This was shortened to "methanol" in 1892 by the International Conference on Chemical Nomenclature. [29] The suffix-yl, which, in organic chemistry, forms names of carbon groups, is from the word methyl.
It can be synthesized from eugenol and has been used in the manufacture of vanillin. It may occur as either the cis (Z) or trans (E) isomer. Trans (E) isoeugenol is crystalline while cis (Z) isoeugenol is a liquid. [6] Isoeugenol is one of several phenolic compounds responsible for the mold-inhibiting effect of smoke on meats and cheeses.

Vanillin was first synthesized from eugenol (found in oil of clove) in 1874–75, less than 20 years after it was first identified and isolated. Vanillin was commercially produced from eugenol until the 1920s. [37] Later it was synthesized from lignin-containing "brown liquor", a byproduct of the sulfite process for making wood pulp. [12]
