Deodar Cedar
''Cedrus deodara'', the deodar cedar, Himalayan cedar, or deodar, is a species of cedar native to the Himalayas. Description It is a large evergreen coniferous tree reaching tall, exceptionally with a trunk up to in diameter. It has a conic crown with level branches and drooping branchlets. The leaves are needle-like, mostly long, occasionally up to long, slender ( thick), borne singly on long shoots, and in dense clusters of 20–30 on short shoots; they vary from bright green to glaucous blue-green in colour. The female cones are barrel-shaped, long and broad, and disintegrate when mature (in 12 months) to release the winged seeds. The male cones are long, and shed their pollen in autumn. Chemistry The bark of ''Cedrus deodara'' contains large amounts of taxifolin. The wood contains cedeodarin, ampelopsin, cedrin, cedrinoside, and deodarin (3′,4′,5,6-tetrahydroxy-8-methyl dihydroflavonol). The main components of the needle essential oil include α-terpine ...

Matairesinol
Matairesinol is an organic compound. It is classified as a lignan, i.e., a type of phenylpropanoid. It is present in some cereals, e.g. rye, and together with Secoisolariciresinol, has attracted much attention for its beneficial nutritional effects. Metabolism The plant lignans are precursors of the enterolignans (mammalian lignans). A number of plant lignans are metabolized to the enterolignans (enterodiol and enterolactone) that can potentially reduce the risk of certain cancers and cardiovascular diseases. Biomedical considerations Although some studies attribute disease preventative (cardio-protective and hormone associated cancers like breast cancer) benefits of lignans, the results are inconclusive. Matairesinol has been found to act as an agonist of the adiponectin receptor 1 Adiponectin receptor 1 (AdipoR1) is a protein which in humans is encoded by the ''ADIPOR1'' gene. It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR1. St ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Isopimaric Acid
Isopimaric acid (IPA) is a toxin which acts as a large conductance Ca2+-activated K+ channel (BK channel) opener. Sources IPA originates from many sorts of trees, especially conifers. Chemistry IPA is one of the members of the resin acid group and it is a tricyclic diterpene. Target IPA acts on the large-conductance calcium activated K+ channels (BK channels). Mode of action BK channels are formed by α subunits and accessory β subunits arranged in tetramers. The α subunit forms the ion conduction pore and the β subunit contributes to channel gating. IPA interaction with the BK channel enhances Ca2+ and / or voltage sensitivity of the α subunit of BK channels without affecting the channel conductance. In this state BK channels can still be inhibited by one of their inhibitors, like charybdotoxin (CTX). Opening of the BK channel leads to an increased K+-efflux which hyperpolarizes the resting membrane potential, reducing the excitability of the cell in which the BK-chann ...

Lignan
The lignans are a large group of low molecular weight polyphenols found in plants, particularly seeds, whole grains, and vegetables. The name derives from the Latin word for "wood". Lignans are precursors to phytoestrogens. They may play a role as antifeedants in the defense of seeds and plants against herbivores. Biosynthesis and metabolism Lignans and lignin differ in their molecular weight, the former being small and soluble in water, the latter being high polymers that are undigestable. Both are polyphenolic substances derived by oxidative coupling of monolignols. Thus, most lignans feature a C18 cores, resulting from the dimerization of C9 precursors. The coupling of the lignols occurs at C8. Eight classes of lignans are: "furofuran, furan, dibenzylbutane, dibenzylbutyrolactone, aryltetralin, arylnaphthalene, dibenzocyclooctadiene, and dibenzylbutyrolactol." Many lignans are metabolized by mammalian gut microflora, producing so-called enterolignans. Food sources Flax s ...

Eugenol
Eugenol is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf. It is present in concentrations of 80–90% in clove bud oil and at 82–88% in clove leaf oil. Eugenol has a pleasant, spicy, clove-like scent. The name is derived from ''Eugenia caryophyllata'', the former Linnean nomenclature term for cloves. The currently accepted name is ''Syzygium aromaticum''. Biosynthesis The biosynthesis of eugenol begins with the amino acid tyrosine. L-tyrosine is converted to ''p''-coumaric acid by the enzyme tyrosine ammonia lyase (TAL). From here, ''p''-coumaric acid is converted to caffeic acid by ''p''-coumarate 3-hydroxylase using oxygen and NADPH. ''S''-Adenosyl methionine (SAM) is then used to methylate caffeic acid, forming ferulic acid, which is in turn converted to feruloyl- CoA by ...

Caryophyllene
Caryophyllene (), more formally (−)-β-caryophyllene, (BCP), is a natural bicyclic sesquiterpene that is a constituent of many essential oils, especially clove oil, the oil from the stems and flowers of '' Syzygium aromaticum'' (cloves), the essential oil of ''Cannabis sativa'', rosemary, and hops. It is usually found as a mixture with isocaryophyllene (the ''cis'' double bond isomer) and α-humulene (obsolete name: α-caryophyllene), a ring-opened isomer. Caryophyllene is notable for having a cyclobutane ring, as well as a ''trans''-double bond in a 9-membered ring, both rarities in nature. β-Caryophyllene acts as a full agonist of the Cannabinoid receptor type 2 (CB2 receptor) in rats. β-Caryophyllene has a binding affinity of Ki = 155nM at the CB2 receptors in mice. β-Caryophyllene has been shown to have anti-inflammatory action linked to its CB2 receptor activity in a study comparing the pain killing effects in mice with and without CB2 receptors with the group of mice w ...

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

Limonene
Limonene is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the oil of citrus fruit peels. The -isomer, occurring more commonly in nature as the fragrance of oranges, is a flavoring agent in food manufacturing. It is also used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products. The less common -isomer has a piny, turpentine-like odor, and is found in the edible parts of such plants as caraway, dill, and bergamot orange plants. Limonene takes its name from Italian ''limone'' ("lemon"). Limonene is a chiral molecule, and biological sources produce one enantiomer: the principal industrial source, citrus fruit, contains -limonene ((+)-limonene), which is the (''R'')-enantiomer. Racemic limonene is known as dipentene. -Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation. Chemical reactions Limon ...

Linalool
Linalool () refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. 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 example, as a major constituent of the essential oils of coriander (''Coriandrum sativum'' L.), cymbopo ...
