Webb13 apr. 2024 · Carvacrol and thymol are structural isomers with a hydroxyl group positioned at different positions relative to the phenolic ring and represent ones of the most common and well-known terpenoids, namely terpenes with added oxygen molecules or that have had their methyl groups moved or removed by specific enzymes . Webb15 okt. 2024 · The tested terpenoids included menthol, thymol, camphor, borneol, and trans-sobrerol. Thymol affected the mixtures significantly due to an “acidic proton” on its hydroxyl (OH) group; menthol, with a higher capacity to accept bonding, interacted strongly with thymol. Camphor was the least likely terpene to act as a donor.
