Anacardic Acids
Anacardic acids are phenolic lipids, chemical compounds found in the shell of the cashew nut (''Anacardium occidentale''). An acid form of urushiol, they also cause an allergic skin rash on contact, known as urushiol-induced contact dermatitis. Anacardic acid is a yellow liquid. It is partially miscible with ethanol and ether, but nearly immiscible with water. Chemically, anacardic acid is a mixture of several closely related organic compounds. Each consists of a salicylic acid substituted with an alkyl chain that has 15 or 17 carbon atoms. The alkyl group may be saturated or unsaturated; anacardic acid is a mixture of saturated and unsaturated molecules. The exact mixture depends on the species of the plant. The 15-carbon unsaturated side chain compound found in the cashew plant is lethal to Gram-positive bacteria. Folk use for tooth abscesses, it is also active against acne, some insects, tuberculosis, and MRSA. It is primarily found in foods such as cashew nuts, cashew apple ...

Mango
A mango is an edible stone fruit produced by the tropical tree '' Mangifera indica''. It originated from the region between northwestern Myanmar, Bangladesh, and northeastern India. ''M. indica'' has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus '' Mangifera'' also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion. Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color, which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh. Etymology The English word ''mango'' (plural ''mangoes'' or ''mangos'') originated in the 16th century from the Portuguese ...

Totarol
Totarol is a naturally produced diterpene that is bioactive. It was first isolated by McDowell and Easterfield from the heartwood of ''Podocarpus totara'', an endemic conifer species found in New Zealand. ''Podocarpus totara'' was investigated for unique molecules due to the tree's increased resistance to rotting. Recent studies have confirmed totarol's unique antimicrobial and therapeutic properties. Consequently, totarol is a candidate for a new source of drugs and has been the goal of numerous syntheses. Discovery Totarol was discovered in 1910 by New Zealand scientist Sir Thomas Hill Easterfield. While investigating the properties of '' Miro'', ''Kahikatea'', ''Rimu'', '' Matai'' and ''Tōtara'', Easterfield detected a "crystalline bloom" on tōtara boards a few hours after leaving the planing machine. After extraction of totarol from ''Podocarpus totara,'' Easterfield observed no other compound had been cited in chemical literature before with this formula. Easterfiel ...

In Vitro
''In vitro'' (meaning ''in glass'', or ''in the glass'') Research, studies are performed with Cell (biology), cells or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants. Definition ''In vitro'' (Latin language, Latin for "in glass"; often not italicized in English usage) studies are conducted ...

Linalool
Linalool () refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. Together with geraniol, nerol, and citronellol, linalool is one of the rose alcohols. Linalool has multiple commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). A colorless oil, linalool is classified as an acyclic monoterpenoid. In plants, it is a metabolite, a volatile oil component, an antimicrobial agent, and an aroma compound. Linalool has uses in manufacturing of soaps, fragrances, food additives as flavors, household products, and insecticides. Esters of linalool are referred to as linalyl, e.g. linalyl pyrophosphate, an isomer of geranyl pyrophosphate. The word ''linalool'' is based on '' linaloe'' (a type of wood) and the suffix '. In food manufacturing, it may be called ''coriandrol''. Occurrence Both enantiomeric forms are found in nature: (''S'')-linalool is found, for exam ...

Anise
Anise (; '), also called aniseed or rarely anix, is a flowering plant in the family Apiaceae native to the eastern Mediterranean region and Southwest Asia. The flavor and aroma of its seeds have similarities with some other spices and herbs, such as star anise, fennel, liquorice, and tarragon. It is widely cultivated and used to flavor food, candy, and alcoholic drinks, especially around the Mediterranean. Etymology The name "anise" is derived via Old French from the Latin words or from Greek ''ánēthon'' referring to dill. An obsolete English word for anise is ''anet'', also coming from ''anīsum''. Botany Anise is an herbaceous annual plant growing to or more. The leaves at the base of the plant are simple, long and shallowly lobed, while leaves higher on the stems are feathery or lacy, pinnate, divided into numerous small leaflets. Both leaves and flowers are produced in large, loose clusters. The flowers are either white or yellow, approximately in diameter ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Coast (region)
The Gold Coast was the name for a region on the Gulf of Guinea in West Africa that was rich in gold, petroleum, sweet crude oil and natural gas. This former region is now known as the country Ghana. Etymology and position The Gold Coast, Slave Coast of West Africa, Slave Coast, Pepper Coast (or Grain Coast) and Ivory Coast were named after the main export resources found there, respectively. Early uses of the term ''Gold Coast'' refer strictly to the coast and not the interior. It was not until the 19th century that the term came to refer to areas that are far from the coast. The Gold Coast was to the east of the Ivory Coast and to the west of the Slave Coast of West Africa, Slave Coast. Territorial entities Gold Coast region territorial entities were: * Portuguese Gold Coast (Portuguese people, Portuguese, 1482–1642) * Dutch Gold Coast (Dutch people, Dutch, 1598–1872) * Swedish Gold Coast (Swedes, 1650–1658; 1660–1663) * Couronian colonization, Couronian Gold C ...

Cardanol
Cardanol is a phenolic lipid obtained from anacardic acid, the main component of cashew nutshell liquid (CNSL), a byproduct of cashew nut processing. Cardanol finds use in the chemical industry in resins, coatings, frictional materials, and surfactants used as pigment dispersants for water-based inks. It is used to make phenalkamines, which are used as curing agents for the durable epoxy coatings used on concrete floors. The name of the substance is derived by contraction from the genus '' Anacardium'', which includes the cashew tree, ''Anacardium occidentale''. The name of the genus itself is based on the Greek word for ''heart''. Friction particles are made by polymerizing the unsaturated side chain of cardanol, followed by cross-polymerization with formaldehyde to yield a cardanol-formaldehyde resin by a process analogous to the formation of phenol-formaldehyde resins such as Bakelite. Cardanol-phenol resins were developed in the 1920s by Mortimer T. Harvey, then a student ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
