Coumarin appears as colorless crystals, flakes or colorless to white powder with a pleasant fragrant vanilla odor and a bitter aromatic burning taste. (NTP, 1992) Coumarin is a chromenone having the keto group located at the 2-position. It has a role as a fluorescent dye, a plant metabolite and a human metabolite. Coumarin is a natural product found in Eupatorium cannabinum, Eupatorium japonicum, and other organisms with data available. Coumarin is o hydroxycinnamic acid. Pleasant smelling compound found in many plants and released on wilting. Has anticoagulant activity by competing with Vitamin K. Coumarin is a chemical compound/poison found in many plants, notably in high concentration in the tonka bean, woodruff, and bison grass. It has a sweet scent, readily recognised as the scent of newly-mown hay. It has clinical value as the precursor for several anticoagulants, notably warfarin. --Wikipedia. Coumarins, as a class, are comprised of numerous naturally occurring benzo-alpha-pyrone compounds with important and diverse physiological activities. The parent compound, coumarin, occurs naturally in many plants, natural spices, and foods such as tonka bean, cassia (bastard cinnamon or Chinese cinnamon), cinnamon, melilot (sweet clover), green tea, peppermint, celery, bilberry, lavender, honey (derived both from sweet clover and lavender), and carrots, as well as in beer, tobacco, wine, and other foodstuffs. Coumarin concentrations in these plants, spices, and foods range from <1 mg/kg in celery, 7000 mg/kg in cinnamon, and up to 87,000 mg/kg in cassia. An estimate of human exposure to coumarin from the diet has been calculated to be 0.02 mg/kg/day. Coumarin is used as an additive in perfumes and fragranced consumer products at concentrations ranging from <0.5\\\\% to 6.4\\\\% in fine fragrances to <0.01\\\\% in detergents. An estimate for systemic exposure of humans from the use of fragranced cosmetic products is 0.04 mg/kg BW/day, assuming complete dermal penetration. The use of coumarin as a food additive was banned by the FDA in 1954 based on reports of hepatotoxicity in rats. Due to its potential hepatotoxic effects in humans, the European Commission restricted coumarin from naturals as a direct food additive to 2 mg/kg food/day, with exceptions granting higher levels for alcoholic beverages, caramel, chewing gum, and certain traditional foods. In addition to human exposure to coumarin from dietary sources and consumer products, coumarin is also used clinically as an antineoplastic and for the treatment of lymphedema and venous insufficiency. Exposure ranges from 11 mg/day for consumption of natural food ingredients to 7 g/day following clinical administration. Although adverse effects in humans following coumarin exposure are rare, and only associated with clinical doses, recent evidence indicates coumarin causes liver tumors in rats and mice and Clara cell toxicity and lung tumors in mice. The multiple effects as well as the ongoing human exposure to coumarin have resulted in a significant research effort focused on understanding the mechanism of coumarin induced toxicity/carcinogenicity and its human relevance. These investigations have revealed significant species differences in coumarin metabolism and toxicity such that the mechanism of coumarin induced effects in rodents, and the relevance of these findings for the safety assessment of coumarin exposure in humans are now better understood. In October 2004, the European Food Safety Authority (EFSA, 2004) reviewed coumarin to establish a tolerable daily intake (TDI) in foods. EFSA issued an opinion indicating that coumarin is not genotoxic, and that a threshold approach to safety assessment was most appropriate. EFSA recommended a TDI of 0 to 0.1 mg/kg BW/day. Including dietary contributions, the total human exposure is estimated to be 0.06 mg/kg/day. As a pharmaceutical, coumarin has been used in diverse applications with a wide variety of dosing regimens. Unlike coumadin and ... Coumarin belongs to the class of chemicals known as chromenones. Specifically it is a chromenone having the keto group located at the 2-position. A chromenone is a benzene molecule with two adjacent hydrogen atoms replaced by a lactone-like chain forming a second six-membered heterocycle that shares two carbons with the benzene ring. Coumarin is also described as a benzopyrone and is considered as a lactone.

C10H18O (154.1358)


3,7-Dimethyl-1,6-octadien-3-ol, also known simply as linalool is a naturally occurring terpene alcohol. It belongs to the class of organic compounds known as acyclic monoterpenoids. These are monoterpenes that do not contain a cycle. Linalool has a role as a plant metabolite, a volatile oil component, an antimicrobial agent and a fragrance. There are two stereoisomers of Linalool ‚Äö√Ñ√¨ (S)-linalool and (R)-linalool. Linalool is used as a scent in 60\\\\\% to 80\\\\\% of perfumed hygiene products and cleaning agents including soaps, detergents, shampoos, and lotions. Linalool is also used by pest professionals as a flea, fruit fly, and cockroach insecticide. Linalool is found in more than 200 different species of plants, including many flowers and spice plants. (S)-linalool is found, for example, as a major constituent of the essential oils of coriander (Coriandrum sativum L.), cymbopogon (Cymbopogon martini var. martinii), and sweet orange (Citrus sinensis) flowers. (R)-linalool is present in lavender (Lavandula officinalis), bay laurel (Laurus nobilis), and sweet basil (Ocimum basilicum), among others. Linalool is also found in plants from the Lamiaceae family (mint and other herbs), Lauraceae (laurels, cinnamon, rosewood), Cinnamomum tamala, Solidago Meyen, Artemisia vulgaris (mugwort), Humulus lupulus. Linalool is also one of several monoterpenes that are found in cannabis plants (PMID:6991645 ). There are more than 140 known terpenes in cannabis and the combination of these terepenoids produces the skunky, fruity odor characteristic of C. savita. Like the majority of monoterpenes, linalool starts with the condensation of dimethylallyl diphosphate (DMAPP) and isopentenyl diphosphate (IPP) to form geranyl pyrophosphate (GPP) (PMID:7640522 ). Linalool is then synthesized with the aid of linalool synthase (LIS) (PMID:12572612 ). Linalool has a citrus, floral, rose, woody aroma and a citrus, orange, waxy taste. Linalool is found in a few different foods and spices, such as spearmints, corianders, common thymes, limes, grapes, lemons, grapefruit, oranges, pineapples, blackcurrants, basil, and common oregano. This could make, Linalool a potential biomarker for the consumption of these foods. Linalool is also synthesized, de novo, by yeast (C. cerevisiae) and may contribute to the floral tones found in some wines (PMID:15668008 ). Linalool is a monoterpenoid that is octa-1,6-diene substituted by methyl groups at positions 3 and 7 and a hydroxy group at position 3. It has been isolated from plants like Ocimum canum.

Methyleugenol, also known as 4-allylveratrole or eugenol methyl, belongs to the class of organic compounds known as dimethoxybenzenes. These are organic aromatic compounds containing a monocyclic benzene moiety carrying exactly two methoxy groups. FDA noted the action was despite its continuing stance that this substance does not pose a risk to public health under the conditions of its intended use. Methyleugenol is a sweet, anise, and apricot tasting compound. Methyleugenol is found, on average, in the highest concentration within a few different foods, such as allspices, tarragons, and sweet bay and in a lower concentration in sweet basils, rosemaries, and hyssops. Methyleugenol has also been detected, but not quantified, in several different foods, such as soy beans, evergreen blackberries, muskmelons, citrus, and pomes. This could make methyleugenol a potential biomarker for the consumption of these foods. 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 provided data demonstrating that these additives induce cancer in laboratory animals. Methyleugenol is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. 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. Their ability to attract insects, particularly Bactrocera fruit 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. 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. Methyleugenol is a clear colorless to pale yellow liquid with a spicy earthy odor. Bitter burning taste.
