Oritin is a flavan-3-ol, a type of flavonoid. It is a component of the proteracacinidin tannins of Acacia galpinii and Acacia caffra ( Senegalia caffra ). [1] [2]
Flavan-3-ols are derivatives of flavans that use the 2-phenyl-3,4-dihydro-2H-chromen-3-ol skeleton. These compounds include catechin, epicatechin gallate, epigallocatechin, epigallocatechin gallate, proanthocyanidins, theaflavins, thearubigins.
Flavonoids are a class of plant and fungus secondary metabolites.
Proteracacinidins are polymeric condensed tannins composed of mesquitol. This type of tannin can be found in Acacia caffra.
Catechin is a flavan-3-ol, a type of natural phenol and antioxidant. It is a plant secondary metabolite. It belongs to the group of flavan-3-ols, part of the chemical family of flavonoids.
Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, and grains; red onions and kale are common foods containing appreciable content of quercetin. Quercetin has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods.
Naringenin is a flavorless, colorless flavanone, a type of flavonoid. It is the predominant flavanone in grapefruit, and is found in a variety of fruits and herbs.
Troxerutin is a flavonol, a type of flavonoid, derived from rutin. It is more accurately a hydroxyethylrutoside. It can be isolated from Sophora japonica, the Japanese pagoda tree.
Baicalein (5,6,7-trihydroxyflavone) is a flavone, a type of flavonoid, originally isolated from the roots of Scutellaria baicalensis and Scutellaria lateriflora. It is also reported in Oroxylum indicum and Thyme. It is the aglycone of baicalin. Baicalein is one of the active ingredients of Sho-Saiko-To, a Chinese herbal supplement believed to enhance liver health.
Orientin is a flavone, a chemical flavonoid-like compound. It is the 8-C glucoside of luteolin.
Fisetin (7,3′,4′-flavon-3-ol) is a plant polyphenol from the flavonoid group. It can be found in many plants, where it serves as a colouring agent. It is also found in many fruits and vegetables, such as strawberries, apples, persimmons, onions and cucumbers. Its chemical formula was first described by Austrian chemist Josef Herzig in 1891.
Galangin is a flavonol, a type of flavonoid.
Ononin is an isoflavone glycoside, the 7-O-β-D-glucopyranoside of formononetin, which in turn is the 4'-O-methoxy derivative of the parent isoflavone daidzein.
Taxifolin (5,7,3',4'-flavan-on-ol), also known as dihydroquercetin, belongs to the subclass flavanonols in the flavonoids, which in turn is a class of polyphenols.
Ampelopsin, also known as dihydromyricetin, is a flavanonol, a type of flavonoid. It is found in the Ampelopsis species japonica, megalophylla, and grossedentata; Cercidiphyllum japonicum; Hovenia dulcis; Rhododendron cinnabarinum; some Pinus species; and some Cedrus species, as well as in Salix sachalinensis.
Cynaroside is a flavone, a flavonoid-like chemical compound. It is a 7-O-glucoside of luteolin.
The O-methylated flavonoids or methoxyflavonoids are flavonoids with methylations on hydroxyl groups. O-methylation has an effect on the solubility of flavonoids.
Prenylated flavonoids or prenylflavonoids are a sub-class of flavonoids. They are widely distributed throughout the plant kingdom. Some are known to have phytoestrogenic or antioxidant properties. They are given in the list of adaptogens in herbalism. Chemically they have a prenyl group attached to their flavonoid backbone. It is usually assumed that the addition of hydrophobic prenyl groups facilitate attachment to cell membranes. Prenylation may increase the potential activity of its original flavonoid.
Herbacetin is a flavonol, a type of flavonoid.
Senegalia caffra, also known as hook-thorn or Acacia caffra, is a tree that occurs commonly in southern Africa. Though it is cultivated, it often occurs naturally in Gauteng suburban gardens, together with Acacia karroo and Acacia robusta.
7,8-Dihydroxyflavone (7,8-DHF) is a naturally occurring flavone found in Godmania aesculifolia, Tridax procumbens, and primula tree leaves. It has been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF). 7,8-DHF is both orally bioavailable and able to penetrate the blood–brain barrier. A prodrug of 7,8-DHF with greatly improved potency and pharmacokinetics, R13, is under development for the treatment of Alzheimer's disease.
Promelacacinidin is a polymeric condensed tannin composed of mesquitol. This type of tannin can be found in Senegalia caffra.
Blumeatin is a flavanone found in Blumea balsamifera, and has been reported to be present in Artemisia annua.
