Hesperetin (5,7,3',4'-OMe-flavan-on) is the 4'-methoxy derivative of eriodictyol, a flavanone. Hesperetin's 7-O-glycoside, hesperidin, is a naturally occurring flavanon-glycoside, the main flavonoid in lemons and sweet oranges. Hesperetin (and naringenin, the parent flavanone of naringin) are not found to a significant extent in Citrus spp.

A variety of glycosides of hesperetin are known, including:

Hesperidin 6-O-α-L-rhamnosyl-β-D-glucosidase is an enzyme that uses hesperidin and H₂O to produce hesperetin and rutinose. It is found in the hyphomycetes species Stilbella fimetaria.
