Description

General description

Quercetin is a polyphenolic flavonoid, found in food including onions, asparagus, buckwheat, radish leaves, green tea, cranberry, broccoli, apple, blueberry, and coriander. Quercetin shows strong intramolecular H-binding, which contributes to the bioavailability and transport of the compound. This explains the biological multi-functional nature of the compound and allows for the formation of strong complexes, frequently with metals.[1] Quercetin inhibits cellular proliferation and minimizes DNA damage. Among its many cardiovascular protection properties, quercetin has antioxidant and antiplatelet properties as well as antiplatelet and anti-muscle cell proliferation and migration. It also enhances cardiac cell mitochondrial function and inhibits NF-κB. Numerous animal studies involving dietary quercetin supplementation have shown a protective effect against cardiac problems.[2]

Application

• Quercetin has been used as an antioxidant which reversed the immunosuppressive effects of high glucose and hyperglycemic sera in type 2 diabetic patients.[3]
• It has been used as a detoxifying phytochemical in Apis mellifera.[4]
• It has been used as a positive control in DPPH (2,2- diphenyl-1-picryhydrazyl) radical scavenging assay. It has also been used for the preparation of calibration curve to determine total flavonoid content.[5]

Biochem/physiol Actions

Quercetin is a flavonoid with anticancer activity. Quercetin is a mitochondrial ATPase and phosphodiesterase inhibitor. It Inhibits PI3-kinase activity and slightly inhibits PIP kinase activity. Quercetin has antiproliferative effects on cancer cell lines, reduces cancer cell growth via type II estrogen receptors, and arrests human leukemic T cells in late G1 phase of the cell cycle. Quercetin may also inhibit fatty acid synthase activity.
