Do you really know anything about the mysterious quercetin?

Quercetin is a flavonoid widely found in vegetables and fruits. It has the biological activity of anti-free radical, anti-oxidation, anti-bacteria, anti-inflammatory and anti-allergic. It is widely used in medicine, food and cosmetics.


  1. Anti-free radical effect, quercetin inhibits the activity of lipid oxidase in cell membrane, which can inhibit the lipid peroxidation process of cell membrane and protect cells from peroxidation. Quercetin is a superoxide anion radical trapping agent, complexing iron ions and preventing free radicals from being produced in the body.
  2. Antioxidant effect, quercetin contains more phenolic hydroxyl groups, easy to oxidize and provide proton H+, with phenolic antioxidant properties.
