Methyl Isoeugenol
Methyl isoeugenol (isomethyleugenol) is a phenylpropanoid, the methyl ether of isoeugenol, found in certain essential oils. It can occur as both (''E'')- and (''Z'')-isomers. See also * Methyl eugenol Methyl eugenol (allylveratrol) is a natural chemical compound classified as a phenylpropene, a type of phenylpropanoid. It is the methyl ether of eugenol and is important to insect behavior and pollination. It is found in various essential oils. ...

Phenylpropanoid
The phenylpropanoids are a diverse family of organic compounds that are synthesized by plants from the amino acids phenylalanine and tyrosine. Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis. From 4-coumaroyl-CoA emanates the biosynthesis of myriad natural products including lignols (precursors to lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. The coumaroyl component is produced from cinnamic acid. Phenylpropanoids are found throughout the plant kingdom, where they serve as essential components of a number of structural polymers, provide protection from ultraviolet light, defend against herbivores and pathogens, and also mediate plant-pollinator interactions as floral pigments and scent compounds. Hydroxycinnamic acids Phenylalanine is first converted to cinnamic aci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoeugenol
Isoeugenol is a phenylpropene, a propenyl-substituted guaiacol. A phenylpropanoid, it occurs in the essential oils of plants such as ylang-ylang (''Cananga odorata''), and is a component of wood smoke and liquid smoke. 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. Isoeugenol is one of several phenolic compounds responsible for the mold-inhibiting effect of smoke on meats and cheeses. Allergy Some individuals experience a hives-like reaction to long-term exposure to Isoeugenol, which is named as ''Fragrance'' in the ingredients of consumer products such as soaps, shampoos and detergents, bath tissue, and topical cosmetic applications. Sensitivity to isoeugenol (Fragrance) may be identified with a clinical patch test. See also * Pseudoisoeugenol * Methylisoeugenol * Desmethylisoeugenol Hydroxychavi ...

Essential Oil
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean indispensable or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, air ...

Methyl Eugenol
Methyl eugenol (allylveratrol) is a natural chemical compound classified as a phenylpropene, a type of phenylpropanoid. It is the methyl ether of eugenol and is important to insect behavior and pollination. 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 component of floral fragrance. Their ability to attract insects, particularly '' Bactrocera'' fruit flies (particularly, ''Bactrocera dorsalis'' male flies) was first noticed in 1915 by F. M. Howlett. The compound may have evolved in response to pathogens, as methyl eugenol has some antifungal activity. It also repels many insects. As of October 2018, the US FDA withdrew authorization for the use of methyl eugenol as a synthetic flavoring substance for use in food because petitioners (including the Natural Resources Defense Coun ...
