Eleutherococcus Senticosus
''Eleutherococcus senticosus'' is a species of small, woody shrub in the family Araliaceae native to Northeastern Asia. It may be colloquially called devil's bush, Siberian ginseng, taiga root, eleuthero, ''ciwujia'', ''Devil's shrub'', ''shigoka'', ''touch-me-not'', ''wild pepper'', or ''kan jang''. ''E. senticosus'' has a history of use in folklore and traditional Chinese medicine. Root extracts of ''E. senticosus'' are sold as a dietary supplement or cosmetics, cosmetic, usually under the name ''Siberian ginseng''. Etymology The scientific name (genus), ''Eleutherococcus'' (from Greek) means "free-berried," and ''senticosus'', (from Latin) means ''sentis'' (thorn-bush, briar), an adjective meaning "thorny" or "full of briers or thorns." It is not the same plant as American ginseng (''Panax quinquefolius'') or Asian ginseng (''Panax ginseng''). It has a diversity of common names across its range of distribution.

Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caffeic Acid
Caffeic acid is an organic compound with the formula . It is a polyphenol with a key role in scavenging reactive oxygen species (ROS) generated in energy metabolism. Caffeic acid is also one major polyphenol responsible for maintaining normal levels of nitric oxide (NO) within cells. Caffeic acid is a yellow, solid chemical compound that is structually classified as a hydroxycinnamic acid, and the molecule consists of both phenolic and acrylic functional groups. Caffeic acid is found in all plants as an intermediate in the biosynthesis of lignin, a naturally occurring complex carbohydrate representing the principal components of biomass and its residues. It is chemically unrelated to caffeine; instead, the shared name is related to its presence in coffee. Natural occurrences Caffeic acid can be found in the bark of ''Eucalyptus globulus'' the barley grain ''Hordeum vulgare'' and the herb '' Dipsacus asperoides''. It can also be found in the freshwater fern '' Salvinia molest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphenol
Polyphenols () are a large family of naturally occurring phenols. They are abundant in plants and structurally diverse. Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning (leather), tanning garments. Etymology The name derives from the Ancient Greek word (, meaning "many, much") and the word ‘phenol’ which refers to a chemical structure formed by attachment of an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group (hence the ''-ol'' suffix). The term "polyphenol" has been in use at least since 1894. Definition Polyphenols are natural products with "one or several hydroxyl groups on aromatic rings", including four principal classes: phenolic acids, flavonoids, stilbenes, and lignans. Flavonoids can be grouped as flavones, flavonols, flavanols, flavanones, isoflavones, proanthocyanidins, and anthocyanins. Particularly abundant flavanoids in foods are catechin (tea, frui ...

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.

Eleutheroside
Eleutherosides are a diverse group of chemical compounds that were isolated from roots of the herb ''Eleutherococcus senticosus'' which is commercially offered mostly as extracts. Eleutheroside A is a saponin and sterol glycoside while other eleutherosides, such as eleutheroside B (syringin), are phenyl propanoid glycosides. They serve as marker compounds for the Thin layer chromatography identification of ''Eleutherococcus senticosus'' herbal preparations and dietary supplements. Eleutheroside E is an optical isomer of acanthoside D, which is one of the glycosides isolated from the cluster-flowering acanthopanax and represents the di-β-D-glucoside of (−)-syringaresinol Syringaresinol is a lignan found in '' Castela emoryi'', in ''Prunus mume''.

Sesamin
Sesamin is a lignan isolated from the bark of '' Fagara'' plants and from sesame oil Sesame oil is an edible vegetable oil derived from sesame seeds. The oil is one of the earliest-known crop-based oils. Worldwide mass modern production is limited due to the inefficient manual harvesting process required to extract the oil. .... It has been used as a dietary fat-reduction supplement. Its major metabolite is enterolactone, which has an elimination half life of less than 6 hours. Sesamin and sesamolin are minor components of sesame oil, on average comprising only 0.14% of the oil by mass.

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