Hesperetin 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.
Hesperetin is a cholesterol lowering flavanoid found in a number of citrus juices. It appears to reduce cholesteryl ester mass and inhibit apoB secretion by up to 80%. Hesperetin may have antioxidant, anti-inflammatory, anti-allergic, hypolipidemic, vasoprotective and anticarcinogenic actions. Hesperetin is a biomarker for the consumption of citrus fruits.
(±)-Hesperetin is an antioxidant flavonoid. Induces G1-phase cell cycle arrest. Anti-inflammatory. (±)-Hesperetin suppresses NF-κB activation. Reduces cholesterol biosynthesis. Inhibits lipid peroxidation. Neuroprotective against neuronal oxidative damage.
