Poncirin
Poncirin is the 7-O-neohesperidoside of isosakuranetin. Poncirin can be extracted from trifoliate orange The trifoliate orange, ''Citrus trifoliata'' or ''Poncirus trifoliata'', is a member of the family Rutaceae.

Isosakuranetin
Isosakuranetin, an O-methylated flavonoid, is the 4'-methoxy derivative of naringenin, a flavanone. Didymin, a disaccharide of isosakuranetin, occur e.g. in sweet orange, blood orange and mandarin. Isosakuranetin is a potent inhibitor of TRPM3 channels.

Flavanone Glycosides
The flavanones, a type of flavonoids, are various aromatic, colorless ketones derived from flavone that often occur in plants as glycosides. List of flavanones * Blumeatin * Butin * Eriodictyol * Hesperetin * Hesperidin * Homoeriodictyol * Isosakuranetin * Naringenin * Naringin * Pinocembrin * Poncirin * Sakuranetin * Sakuranin * Sterubin * Pinostrobin Metabolism The enzyme chalcone isomerase uses a chalcone-like compound to produce a flavanone. Flavanone 4-reductase is an enzyme that uses (2''S'')-flavan-4-ol The flavan-4-ols (3-deoxyflavonoids) are flavone-derived alcohols and a family of flavonoids. Flavan-4-ols are colorless precursor compounds that polymerize to form red phlobaphene pigments. They can be found in the sorghum. Glycosides (abacopteri ... and NADP+ to produce (2''S'')-flavanone, NADPH, and H+.

Trifoliate Orange
The trifoliate orange, ''Citrus trifoliata'' or ''Poncirus trifoliata'', is a member of the family Rutaceae. Whether the trifoliate oranges should be considered to belong to their own genus, ''Poncirus'', or be included in the genus ''Citrus'' is debated. The species is unusual among citrus for having deciduous, compound leaves and pubescent (downy) fruit. It is native to northern China and Korea, and is also known as the Japanese bitter-orange, hardy orange or Chinese bitter orange. The plant is a fairly cold-hardy citrus (USDA zone 6) and will tolerate moderate frost and snow, making a large shrub or small tree tall. Because of its relative hardiness, citrus grafted onto ''Citrus trifoliata'' are usually hardier than when grown on their own roots. Description The trifoliate orange is recognizable by the large thorns on the shoots, and its deciduous leaves with three (or rarely, five) leaflets, typically with the middle leaflet long, and the two side leaflets long.

Flavonoids Found In Rutaceae
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4-benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins (flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non-k ...
