Astragalin is a chemical compound . It can be isolated from Phytolacca americana ( the American pokeweed ) or in the methanolic extract of fronds of the fern Phegopteris connectilis . It is also found in wine . Astragalin is a 3-O-glucoside of kaempferol .
Kaempferol ( 3,4′,5,7-tetrahydroxyflavone ) is a natural flavonol , a type of flavonoid , found in a variety of plants and plant-derived foods including kale , beans , tea , spinach and broccoli . Kaempferol is a yellow crystalline solid with a melting point of 276-278 °C ( 529-532 °F ) . It is slightly soluble in water and highly soluble in hot ethanol , ethers , and DMSO . Kaempferol acts as an antioxidant by reducing oxidative stress . Many studies suggest that consuming kaempferol may reduce the risk of various cancers , and it is currently under consideration as a possible cancer treatment [ citation needed ] . It is named for 17th-century German naturalist Engelbert Kaempfer .
Azalein is a chemical compound . It is a flavonol , a type of flavonoid . It is the 3-O-α-L-rhamnoside of azaleatin . It can be found in the flowers of Plumbago and Rhododendron species .
Azaleatin is a chemical compound . It is an O-methylated flavonol , a type of flavonoid . It was first isolated from the flowers of Rhododendron mucronatum in 1956 and has since been recorded in forty-four other Rhododendron species , in Plumbago capensis , in Ceratostigma willmottiana and in Carya pecan . It has been also been found in the leaves of Eucryphia .
Hyperoside is a chemical compound . It is the 3-O-galactoside of quercetin .
Quercetin is a plant flavonol from the flavonoid group of polyphenols . It is found in many fruits , vegetables , leaves , seeds , 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 .
Isoquercetin , isoquercitrin or isotrifoliin is a flavonoid , a type of chemical compound . It is the 3-O-glucoside of quercetin . Isoquercitrin can be isolated from various plant species including Mangifera indica ( mango ) and Rheum nobile ( the Noble rhubarb ) . It is also present in the leaves of Annona squamosa and Camellia sinensis ( tea ) .
Kaempferitrin is a chemical compound . It can be isolated from the leaves of Hedyotis verticillata and from Onychium japonicum . Kaempferitrin is the 3,7-dirhamnoside of kaempferol .
Myricitrin is a plant compound , the 3-O-α-L-rhamnopyranoside of myricetin .
Myricetin is a member of the flavonoid class of polyphenolic compounds , with antioxidant properties . Common dietary sources include vegetables ( including tomatoes ) , fruits ( including oranges ) , nuts , berries , tea , and red wine . Myricetin is structurally similar to fisetin , luteolin , and quercetin and is reported to have many of the same functions as these other members of the flavonol class of flavonoids . Reported average intake of myricetin per day varies depending on diet , but has been shown in the Netherlands to average 23 mg/day . Myricetin is produced from the parent compound taxifolin through the ( + ) -dihydromyricetin intermediate and can be further processed to form laricitrin and then syringetin , both members of the flavonol class of flavonoids . Dihydromyricetin is frequently sold as a supplement and has controversial function as a partial GABAA receptor potentiator and treatment in Alcohol Use Disorder ( AUD ) . Myricetin can alternatively be produced directly from kaempferol , which is another flavonol .
Quercitrin is a glycoside formed from the flavonoid quercetin and the deoxy sugar rhamnose . Austrian chemist Heinrich Hlasiwetz ( 1825-1875 ) is remembered for his chemical analysis of quercitrin .
Robinin is a chemical compound . It can be isolated from Vinca erecta or from the common locust Robinia pseudoacacia . It is a flavone glycoside based on kaempferol .
Rutin , also called rutoside , quercetin-3-O-rutinoside and sophorin , is the glycoside combining the flavonol quercetin and the disaccharide rutinose ( α-L-rhamnopyranosyl- ( 1→6 ) -β-D-glucopyranose ) . It is a citrus flavonoid found in a wide variety of plants including citrus fruit .
Spiraeoside is a chemical compound . It can be isolated from flowers of Filipendula ulmaria ( L. ) ( a.k.a . Spiraea ulmaria or meadowsweet ) or from the garden onion ( Allium cepa ) . Spiraeoside is the 4'-O-glucoside of quercetin .
Xanthorhamnin is a chemical compound . It can be isolated from buckthorn berries ( Rhamnus catharticus ) . The aglycone of xanthorhamnin is rhamnetin .
Rhamnetin is an O-methylated flavonol , a type of chemical compound . It can be isolated from cloves . The structure of the molecule was discovered by Austrian chemist Josef Herzig ( 1853-1924 ) .
Amurensin is a flavonol , a type of flavonoid . It is the tert-amyl alcohol derivative of kaempferol 7-O-glucoside . It can be found in Phellodendron amurense .
Icariin is a chemical compound classified as a prenylated flavonol glycoside , a type of flavonoid . It is the 8-prenyl derivative of kaempferol 3,7-O-diglucoside . The compound has been isolated from several species of plant belonging to the genus Epimedium which are commonly known as Horny Goat Weed or Yin Yang Huo . Extracts from these plants are reputed to produce aphrodisiac effects , and are used in traditional Chinese medicine to enhance erectile function . However , clinical trial data are lacking to support these claims .
Kaempferide is an O-methylated flavonol , a type of chemical compound . It can be found in Kaempferia galanga ( aromatic ginger ) . It has been noted to inhibit pancreatic cancer growth by blockading an EGFR-related pathway .
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 . It is used as a vasoprotective . Troxerutin has been shown in mice to reverse CNS insulin resistance and reduce reactive oxygen species induced by a high-cholesterol diet .
