5. Quercetin Benefits

• Anti-oxidation

Quercetin is a superoxide anion scavenger. Its mechanism of anti-free radical and inhibiting lipid oxidation is as follows: It binds iron ions to form inactive complexes; and then it prevents iron ions from participating in biochemical reactions that can produce many free radicals. In the meantime, Quercetin can maintain activity of free radical scavenger of the complexes. There are three main ways that Quercetin prevents free radicals formation: (1) It has complexation capability with superoxide anions to reduce production of oxygen free radicals. (2) It binds iron ions to prevent formation of hydroxyl radicals. (3) Quercetin inhibits aldose reductase, and reduces reduced coenzyme Ⅱ (NADPH) consumption. Thereby, Quercetin improves its anti-oxidation property.

• Anti-bacterial and antivirus

Quercetin can inhibit uncoating of lysosome H⁺-, ATP enzyme and phosphatase A₂. It affects phosphorylation of virus transfer genes. Also, Quercetin inhibits viral protease and RNA synthesis. Therefore, Quercetin has anti-bacterial and anti-viral effect.

• Anti inflammation and anti allergic

Quercetin can inhibit cell lipooxidase and epoxidase, which can restrain synthesis of leukotrienc and prostaglandin. Thus, it acts as an anti-inflammatory and anti-allergic agent.

• Sun protection

The characteristic peaks of ultraviolet absorption of Quercetin are 350nm and 258nm. Quercetin has strong ultraviolet absorption capacity as well as anti-phototoxic effect. It can alleviate sunburn and discoloration caused by sun exposure. Quercetin can be used as sunscreen in cosmetics.
