Aspalathin
Aspalathin is a C-linked dihydrochalcone glucoside found in rooibos tea, a herbal tea prepared from the South African rooibos plant, '' Aspalathus linearis'' (Fabaceae). It was first isolated in 1965 by chromatography In chemical analysis, chromatography is a laboratory technique for the Separation process, separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the ''mobile phase'', which carries it .... It has demonstrated antidiabetic activity.

Rooibos
Rooibos ( ; , ), or , is a broom (shrub), broom-like member of the plant family Fabaceae that grows in South Africa's Fynbos biome. The leaves are used to make a caffeine-free herbal tea, herbal infusion that has been popular in Southern Africa for generations. Since the 2000s, rooibos has gained popularity internationally, with an earthy flavour and aroma that is similar to yerba mate or tobacco. Outside of Southern Africa, it is called bush tea, red tea, or redbush tea (predominantly in Great Britain). The name ''rooibos'' is Afrikaans deriving from , meaning . The name is protected in South Africa and has protected designation of origin status in the EU. Rooibos was formerly classified in the genus but is now thought to be part of , following Rolf Dahlgren, Dahlgren (1980). The specific name (botany), specific name of , for the plant's linear growing structure and needle-like leaves, was given by Nicolaas Laurens Burman, Burman (1759). Production and processing Roo ...

Carbon
Carbon () is a chemical element; it has chemical symbol, symbol C and atomic number 6. It is nonmetallic and tetravalence, tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth's crust. Three Isotopes of carbon, isotopes occur naturally, carbon-12, C and carbon-13, C being stable, while carbon-14, C is a radionuclide, decaying with a half-life of 5,700 years. Carbon is one of the timeline of chemical element discoveries#Pre-modern and early modern discoveries, few elements known since antiquity. Carbon is the 15th abundance of elements in Earth's crust, most abundant element in the Earth's crust, and the abundance of the chemical elements, fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Carbon's abundance, its unique diversity of organic compounds, and its unusual abi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihydrochalcone
Dihydrochalcone (DHC) is the organic compound with the formula C6H5C(O)(CH2)2C6H5. It is the reduced derivative of chalcone (C6H5C(O)(CH)2C6H5). It is a white solid that is soluble in many organic solvents. Dihydrochalcone per se is often minor significance, but some derivatives occur in nature and have attracted attention as drugs.

Glucoside
A glucoside is a glycoside that is chemically derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes. The name was originally given to plant products of this nature, in which the other part of the molecule was, in the greater number of cases, an aromatic aldehydic or phenolic compound (exceptions are Jinigrin and Jalapin or Scammonin). It has now been extended to include synthetic ethers, such as those obtained by acting on alcoholic glucose solutions with hydrochloric acid, and also the polysaccharoses, e.g. cane sugar, which appear to be ethers also. Although glucose is the most common sugar present in glucosides, many are known which yield rhamnose or iso-dulcite; these may be termed pentosides. Much attention has been given to the non-sugar parts (aglycone) of the molecules; the constitutions of many have been determined, and the comp ...

Chromatography
In chemical analysis, chromatography is a laboratory technique for the Separation process, separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the ''mobile phase'', which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the ''stationary phase'' is fixed. Because the different constituents of the mixture tend to have different affinities for the stationary phase and are retained for different lengths of time depending on their interactions with its surface sites, the constituents travel at different apparent velocities in the mobile fluid, causing them to separate. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation. Chromatography may be ''preparative'' or ''analytical' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antidiabetic
Drugs used in diabetes treat types of diabetes mellitus by decreasing glucose levels in the blood. With the exception of insulin, most GLP-1 receptor agonists ( liraglutide, exenatide, and others), and pramlintide, all diabetes medications are administered orally and are thus called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of hypoglycemic drugs, and selection of the appropriate agent depends on the nature of diabetes, age, and situation of the person, as well as other patient factors. Type 1 diabetes or Diabetes mellitus is an endocrine disorder characterized by hyperglycemia due to autoimmune destruction of insulin-secreting pancreatic beta cells or from variable degrees of insulin resistance and deficiency. Chronic hyperglycemia of diabetes can lead to multiorgan damage, resulting in renal, neurologic, cardiovascular, and other serious complications. The treatment for Type 1 diabetes is insulin injection. Type 2 diabetes is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
