Flavanone glycosides

Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone is hesperetin. Its name is derived from the word "hesperidium", for fruit produced by citrus trees.

Naringin is a flavanone-7-O-glycoside between the flavanone naringenin and the disaccharide neohesperidose. The flavonoid naringin occurs naturally in citrus fruits, especially in grapefruit, where naringin is responsible for the fruit's bitter taste. In commercial grapefruit juice production, the enzyme naringinase can be used to remove the bitterness (debittering) created by naringin. In humans naringin is metabolized to the aglycone naringenin (not bitter) by naringinase present in the gut.

Poncirin is the 7-O-neohesperidoside of isosakuranetin. Poncirin can be extracted from trifoliate orange (Poncirus trifoliata).

Sakuranin is a flavanone, a type of flavonoid. It is the O-glucoside of sakuranetin. It can be found in Prunus sp.

Neohesperidin is a flavanone glycoside found in citrus fruits. It is the 7-O-neohesperidose derivative of hesperetin, which in turn is the 4'-methoxy derivative of eriodictyol. Neohesperidin dihydrochalcone has an intense sweet taste, and is listed as a generally recognized as safe flavour enhancer by the Flavor and Extract Manufacturers Association.

Liquiritin is the 4'-O-glucoside of the flavanone liquiritigenin. Liquiritin is one of flavone compounds derived from licorice.

Eriocitrin (eriodictyol glycoside) is a flavanone-7-O-glycoside between the flavanone eriodictyol and the disaccharide rutinose. It is commonly found in lemons and other citrus fruits. It is colloquially called lemon flavonoid or a citrus flavonoid, one of the plant pigments that bring color to fruit and flowers. This antioxidant also predominates (38% in 1 study) in Peppermint infusions.

Narirutin is a flavanone-7-O-glycoside, consisting of the flavanone naringenin bonded with the disaccharide rutinose.

Neoeriocitrin is a 7-O-glycoside of the flavanone eriodictyol and the disaccharide neohesperidose (α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranose). Note that the 'neo' in the name in this case does not refer to the position of the B-ring (which is not in a neo position), but refer to the glycosyl moiety.

Prunin is a flavanone glycoside found in immature citrus fruits and in tomatoes. Its aglycone form is called naringenin.
