Pericón
''Tagetes lucida'' is a perennial plant native to Mexico and Central America. It is used as a medicinal plant and as a culinary herb. The leaves have a tarragon-like scent, with hints of anise, and it has entered the nursery trade in North America as a tarragon substitute. Common names include sweetscented marigold, Mexican marigold, Mexican mint marigold, Mexican tarragon, sweet mace, Texas tarragon, pericón, yerbaniz, and hierbanís. Description ''Tagetes lucida'' grows tall and requires full sun to light shade. Depending on the variety or landrace, the plant may be fairly upright, while other forms appear bushy with many unbranching stems. The leaves are linear to oblong, about long, and shiny medium green, not blue-green as in French tarragon (''Artemisia dracunculus'' var. ''sativa''). In late summer it bears clusters of small golden yellow flower heads on the ends of the stems. The flower heads are about across and have 3–5 golden-yellow ray florets. The flower ...

Maya Peoples
Maya () are an ethnolinguistic group of Indigenous peoples of the Americas, Indigenous peoples of Mesoamerica. The ancient Maya civilization was formed by members of this group, and today's Maya are generally descended from people who lived within that historical region. Today they inhabit southern Mexico, Guatemala, Belize, and westernmost El Salvador, Honduras, and the northernmost Nicaragua. "Maya" is a modern collective term for the peoples of the region; however, the term was not historically used by the Indigenous populations themselves. There was no common sense of identity or political unity among the distinct populations, societies and ethnic groups because they each had their own particular traditions, cultures and historical identity. It is estimated that seven million Maya were living in this area at the start of the 21st century. Guatemala, southern Mexico and the Yucatán Peninsula, Belize, El Salvador, western Honduras, and northern Nicaragua have managed to ma ...

Quercetin
Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; capers, red onions, and kale are common foods containing appreciable amounts of it. It has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods. Occurrence Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived from ''quercetum'' (oak forest), after the oak genus ''Quercus''. It is a naturally occurring polar auxin transport inhibitor. Quercetin is one of the most abundant dietary flavonoids, with an average daily consumption of 25–50 mg. In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration. One study found that organically grown tomatoes had 79% more quercetin than non-organically grown fruit. Quercetin is present in ...

Methyleugenol
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 ...

Isorhamnetin
Isorhamnetin is an O-methylated flavon-ol from the class of flavonoid Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids ...s. A common food source of this 3'-methoxylated derivative of quercetin and its glucoside conjugates are pungent yellow or red onions, in which it is a minor pigment, quercetin-3,4'-diglucoside and quercetin-4'-glucoside and the aglycone quercetin being the major pigments. Pears, olive oil, wine and tomato sauce are rich in isorhamnetin. Almond skin is a rich source of isorhamnetin-3-O-rutinoside and isorhamnetin-3-O-glucoside, in some cultivars they comprise 75% of the polyphenol content, the total of which can exceed 10 mg/100 gram almond. Others sources include the spice, herbal medicinal and psychoactive Mexican tarragon ''( Tagetes lucida)'', which is descri ...

Coumarin
Coumarin () or 2''H''-chromen-2-one is an aromatic organic chemical compound with formula . Its molecule can be described as a benzene molecule with two adjacent hydrogen atoms replaced by an unsaturated lactone ring , forming a second six-membered heterocycle that shares two carbons with the benzene ring. It belongs to the benzopyrone chemical class and is considered a lactone. Coumarin is a colorless crystalline solid with a sweet odor resembling the scent of vanilla and a bitter taste. It is found in many plants, where it may serve as a chemical defense against predators. While coumarin is not an anticoagulant, its 3-alkyl-4-hydroxy derivatives, such as the fungal metabolite dicoumarol, inhibit synthesis of vitamin K, a key component in blood clotting. A related compound, the prescription drug anticoagulant warfarin, is used to inhibit formation of blood clots, deep vein thrombosis, and pulmonary embolism. Etymology Coumarin is derived from , the French word for the ...

Chavicol
Chavicol (''p''-allylphenol) is a natural phenylpropene, a type of organic compound. Its chemical structure consists of a benzene ring substituted with a hydroxy group and a propenyl group. It is a colorless liquid found together with terpenes in betel oil. Properties and reactions Chavicol is miscible with alcohol, ether, and chloroform. Dimerization of chavicol gives the neo-lignan magnolol. Uses Chavicol is used as an odorant in perfumery and as a flavor. It is found in many essential oils, including anise and gardenia. Biosynthesis Chavicol is formed in sweet basil (''Ocimum Basilicum'') by the phenylpropanoid pathway via ''p''-coumaryl alcohol. The allylic alcohol in ''p''-coumaryl alcohol is converted into a leaving group. This then leaves thus forming a cation, this cation can be regarded as a quinone methide which then is reduced by NADPH to form either anol or chavicol. : See also * Estragole, the methyl ether * Safrole Safrole is an organic compound with the ...

Anethole
Anethole (also known as anise camphor) is an organic compound that is widely used as a flavoring substance. It is a derivative of the aromatic compound allylbenzene and occurs widely in the essential oils of plants. It is in the class of phenylpropanoid organic compounds. It contributes a large component of the odor and flavor of anise and fennel (both in the botanical family Apiaceae), anise myrtle (Myrtaceae), liquorice (Fabaceae), magnolia blossoms, and star anise ( Schisandraceae). Closely related to anethole is its isomer estragole, which is abundant in tarragon (Asteraceae) and basil (Lamiaceae), and has a flavor reminiscent of anise. It is a colorless, fragrant, mildly volatile liquid. Anethole is only slightly soluble in water but exhibits high solubility in ethanol. This trait causes certain anise-flavored liqueurs to become opaque when diluted with water; this is called the ouzo effect. Structure and production Anethole is an aromatic, unsaturated ether related to ...
