| Description | Eugenol or 4-allyl-2-methoxyphenol is classified as a phenylpropanoid, formally derived from guaiacol, with an allyl chain positioned para to the hydroxy group. It is soluble in water, alcohol, chloroform, ether and oils. Eugenol is a neutral compound. It is biosynthesized from tyrosine. Eugenol is widely distributed in plants. It is a clear to pale yellow oily liquid extracted from clove oil, nutmeg, cinnamon, basil and bay leaf. It has a pleasant, spicy, clove-like odor with a spicy pungent taste. Eugenol is found in highest concentrations in cloves, allspices, and carrots and in lower concentrations in walnuts, ceylon cinnamons, and wild carrots. Eugenol has also been detected in shea tree, passion fruits, winged beans, fireweeds, and gingers, making it a potential biomarker for the consumption of these foods. Eugenol is used in perfumeries, flavorings and essential oils. It was first used for the manufacture of vanillin (https://doi.org/10.1021/ed054p776), though most vanillin is now produced from petrochemicals or from by-products of paper manufacture. Eugenol is hepatotoxic, meaning it may cause damage to the liver, if consumed in high doses. Eugenol has local antiseptic and anaesthetic properties (PMID:15089054 ; PMID:935250 ) and acts as positive allosteric modulators of the GABA-A receptor. It has high antioxidant, anti-proliferative, and anti-inflammatory activities with potential roles in alleviating and preventing cancer and inflammatory reactions (PMID:27771920 ). |
