Glycosides are compounds that yield one or more sugars among the products of hydrolysis. Glycosides may be considered sugar ethers. The non sugar component is known as the aglycone, and the sugar component is called glycone. The flavonoid glycosides and their aglycones are generally termed flavonoids. Rutin, quercitrin, and the citrus bioflavonoids, including hesperidin, hesperetin, diosmin, and naringen, are among the best known flavonoid constituents. Quercetin is the aglycone of quercitrin, rutin and other flavonoids.
