Quercetin, as the most common flavonoid compound, has various biological activities and can resist oxidation, playing an important role in the clinical treatment of cancer and cardiovascular diseases. Quercetin not only participates in in in vitro antioxidant activity and can inhibit DNA oxidative damage, but also protects tissues from oxidative damage by reducing peroxide concentration in vivo.
Usually packed in 25kg/drum,and also can be do customized package.
