Estragole
Estragole (''p''-allylanisole, methyl chavicol) is a phenylpropene, a natural organic compound. Its chemical structure consists of a benzene ring substituted with a methoxy group and an allyl group. It is an isomer of anethole, differing with respect to the location of the double bond. It is a colorless liquid, although impure samples can appear yellow. It is a component of various trees and plants, including turpentine (pine oil), anise, fennel, bay, tarragon, and basil. It is used in the preparation of fragrances.. The compound is named for ''estragon'', the French name of tarragon. Production Hundreds of tonnes of basil oil are produced annually by steam distillation of ''Ocimum basilicum'' (common basil). This oil is mainly estragole but also contains substantial amounts of linalool. Estragole is the primary constituent of essential oil of tarragon (comprising 60–75%). It is also present in pine oil, turpentine, fennel, anise (2%), ''Clausena anisata'' and '' Syzygi ...

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 ...

Tarragon
Tarragon (''Artemisia dracunculus''), also known as estragon, is a species of perennial herb in the family Asteraceae. It is widespread in the wild across much of Eurasia and North America and is cultivated for culinary and medicinal purposes. One subspecies, ''Artemisia dracunculus'' var. ''sativa'', is cultivated to use the leaves as an aromatic culinary herb. In some other subspecies, the characteristic aroma is largely absent. The species is polymorphic. Informal names for distinguishing the variations include "French tarragon" (best for culinary use), "Russian tarragon," and "wild tarragon" (covers various states). Tarragon grows to tall, with slender branches. The leaves are lanceolate, long and broad, glossy green, with an entire margin. The flowers are produced in small capitula diameter, each capitulum containing up to 40 yellow or greenish-yellow florets. French tarragon, however, seldom produces any flowers (or seeds). Some tarragon plants produce seeds that are ...

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 reagrded as a quinone methide which then is reduced by NADPH to form either anol or chavicol.Daniel G. Vassao, David R.

Syzygium Anisatum
:''Should not be confused with Clausena anisata, a small tree native to Southeast Asia and Australia.'' ''Syzygium anisatum'', with common names ringwood and aniseed tree, is a rare Australian rainforest tree with an aromatic leaf that has an essential oil profile comparable to true aniseed. The leaf from cultivated plantations is used as a bushfood spice and distilled for the essential oil, and is known in the trade as aniseed myrtle or anise myrtle. The ringwood tree has a dense crown and grows up to 45 metres tall. The leaves are 6–12 cm long with prominently undulate margins and rich aniseed aroma when crushed. Flowers are white and sweetly scented, borne in panicles. The fruit are dry papery capsules around 5 mm long and are white in appearance. Ringwood's natural distribution in the wild is restricted to the Nambucca and Bellinger Valleys in the subtropics of New South Wales, Australia. Uses Used as a flavouring spice and herbal tea ingredient. Although ...

Safrole
Safrole is an organic compound with the formula CH2O2C6H3CH2CH=CH2. It is a colorless oily liquid, although impure samples can appear yellow. A member of the phenylpropanoid family of natural products, it is found in sassafras plants, among others. Small amounts are found in a wide variety of plants, where it functions as a natural antifeedant. ''Ocotea pretiosa'', which grows in Brazil, and ''Sassafras albidum'', which grows in eastern North America, are the main natural sources of safrole. It has a characteristic "sweet-shop" aroma. It is a precursor in the synthesis of the insecticide synergist piperonyl butoxide, the fragrance piperonal via isosafrole, and the empathogenic/entactogenic substance MDMA. History Safrole was obtained from a number of plants, but especially from the sassafras tree (''Sassafras albidum''), which is native to North America, and from Japanese star anise (''Illicium anisatum'', called ''shikimi'' in Japan). In 1844, the French chemist Édouard ...

Anethole
Anethole (also known as anise camphor) is an organic compound that is widely used as a flavoring substance. It is a derivative of phenylpropene, a type of aromatic compound that occurs widely in nature, in essential oils. 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, abundant in tarragon (Asteraceae) and basil (Lamiaceae), that 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; the ouzo effect. Structure and production Anethole is an aromatic, unsaturated ether related to lignols. It e ...

Animal Testing On Rodents
Rodents are commonly used in animal testing, particularly mice and rats, but also guinea pigs, hamsters, gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast reproduction rate. __TOC__ Statistics In the UK in 2015, there were 3.33 million procedures on rodents (80% of total procedures that year). The most common species used were mice (3.03 million procedures, or 73% of total) and rats (268,522, or 6.5%). Other rodents species included guinea pigs (21,831 / 0.7%), hamsters (1,500 / 0.04%) and gerbils (278 / 0.01%). In the U.S., the numbers of rats and mice used are not reported, but estimates range from around 11 million to approximately 100 million. In 2000, the Federal Research Division, Library of Congress, published the results of an analysis of its Rats/Mice/and Birds Database: Researchers, Breeders, Transporters, and Exhibitors. Rodent types Mice Mice are the most commonly used v ...
