Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), C 10 H 14 O, is a natural monoterpenoid phenol derivative of p-Cymene, isomeric with carvacrol.It occurs naturally in the oil of thyme, and it is extracted from Thymus vulgaris (common thyme), ajwain, [4] and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties.
In plants, the phenolic units are esterified or methylated and are submitted to conjugation, which means that the natural phenols are mostly found in the glycoside form instead of the aglycone form. In olive oil, tyrosol forms esters with fatty acids. [25] In rye, alkylresorcinols are phenolic lipids. Some acetylations involve terpenes like ...
Thymol is the principal aromatic component of thyme. The chemical composition of Thymus (thyme) includes a variety of essential oils, flavonoids, phenolic acids, triterpenes, and other compounds. The essential oils found in thyme include thymol , which is a major component responsible for the plant's antiseptic properties, and carvacrol ...
[15] [16] Menthol, hinokitiol and thymol are also used in oral hygiene products. Thymol also has antiseptic and disinfectant properties. [17] Volatile monoterpenes produced by plants can attract or repel insects, thus some of them are used in insect repellents, such as citronellol, eucalyptol, limonene, linalool, hinokitiol, menthol and thymol ...

Ajwain or ajowan (Trachyspermum ammi) [3] (/ ˈ æ dʒ ə w ɒ n /) —also known as ajowan caraway, thymol seeds, bishop's weed, or carom—is an annual herb in the family Apiaceae. [4] Both the leaves and the seed ‑like fruit (often mistakenly called seeds) of the plant are consumed by humans.
Ruta graveolens, commonly known as rue, common rue or herb-of-grace, is a species of the genus Ruta grown as an ornamental plant and herb.It is native to the Balkan Peninsula.
The detailed study of reproductive structures in plants led to the discovery of the alternation of generations, found in all plants and most algae, by the German botanist Wilhelm Hofmeister. This discovery is one of the most important made in all of plant morphology, since it provides a common basis for understanding the life cycle of all plants.
