Hesperidin
A flavonoid (a class of polyphenols) glycoside. Hesperidin is a compound frequently ingested in the form of citrus fruits/juices. Hesperidin has antioxidant, anti-diabetic/lipid-modulating and anti-inflammatory effects. Interestingly enough, it also enhances bone-mineral density in animal experiments. Hesperidin may also inhibit the activity of drug metabolizing enzymes and enhance drug bioavailability.
Hesperitin is the aglycone form (i.e., the sugar – or glycoside – moiety is removed).
