α-cadinol
α-Cadinol or 10α-hydroxy-4-cadinene is an organic compound, a sesquiterpenoid alcohol. Natural occurrence This compound is found in essential oils and extracts of many plants, such as *'' Agrotaxis selaginoides'', * ''Tabernaemontana catharinensis'' * '' Litsea acutivena'' (7.7%), * '' Salvia aratocensis'' (20%), * '' Protium giganteum'' (7%), * '' Uvaria ovata'' root bark (13–24%), * '' Plinia trunciflora'' (19%) * '' Tanacetum sonbolii'' (35%) * ''Schisandra chinensis'' berries (5%), * ''Melia azedarach'' (11%), * ''Neolitsea parvigemma'' (10%), * ''Tetradenia riparia'' (8%) Biological activity α-Cadinol was said to act as anti-fungal and as hepatoprotective, and was proposed as a possible remedy for drug-resistant tuberculosis. See also * δ-Cadinol δ-Cadinol is an organic compound, a sesquiterpenoid alcohol produced by many plants as well as some animals and microorganisms.

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

Schisandra Chinensis
''Schisandra chinensis'' (common name: magnolia-vine, Chinese magnolia-vine, schisandra), whose fruit is called magnolia berry or five-flavor-fruit (from Chinese 五味子 ''wǔwèizi''), is a vine plant native to forests of Northern China, the Russian Far East and Korea. Wild varieties are also found in Japan. It is hardy in USDA Zone 4. The fruits are red berries in dense clusters around long. Etymology, common names, and taxonomy The genus ''Schisandra'' was first published by André Michaux in 1803, the name deriving from the Greek words ''schizein'' ('to split') and ''andros'' ('man'), referring to the separate anther cells on the stamens. In the 21st century, ''Schisandra chinensis'' belongs to the family of Schisandraceae. In earlier years, it was assumed that the species belonged to the family of Magnoliaceae, hence the name ''Chinese magnolia-vine''. However, many differences in plant phenology between Schisandra and members of Magnoliaceae led to the formatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary Alcohols
In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl () functional group bound to a saturated carbon atom. The term ''alcohol'' originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula . Simple monoalcohols that are the subject of this article include primary (), secondary () and tertiary () alcohols. The suffix ''-ol'' appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority. When a higher priority group is present in the compound, the prefix ''hydroxy-'' is used in its IUPAC name. The suffix ''-ol'' in non-IUPAC names (such as paracetamol or cholesterol) also typically indicates that the substance is an alcohol. However, some compound ...

Sesquiterpenes
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. Sesquiterpenes are found naturally in plants and insects, as semiochemicals, e.g. defensive agents or pheromones. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can l ...
