Product Introduction
Production Introduction
Pure natural quercetin is a flavonol compound. Pure natural quercetin is widely found in the stem, flower, leaf, bud, seed and fruit of many plants, mostly in the form of glycosides, such as rutin, quercetin, hypericin, etc. Quercetin can be obtained by acid hydrolysis. We specialize in research the quercetin that extract from the rutin. Quercetin used in pharmaceutical and healthcare additives.

What Main Functions of Rutin Extract?
●It is an antioxidant:
Quercetin is a natural chelating agent that can chelate iron in the body, reduce the iron overload in the body, reduce the oxidative damage caused by iron overload.
●Inhibition of tumor activity:
In numerous studies, pure natural quercetin is a variety of biological effects, inhibit a variety of enzymes in cancer cells involved in cell proliferation and signal transduction pathways. On the other hand, some studies have shown that quercetin has a certain synergistic effect in combination with common chemotherapy agents or radiotherapy, and has a certain application prospect.
●It has good effect on antiviral activity:
It can significantly decrease the rate of the replication of hepatitis c virus (HCV), also found that after quercetin treatment of infectious virus particles was reduced by 65%, it showed affect the integrity of the virus, further confirmed by molecular experiments it plays a role of antivirus because it used to prevent hepatitis c virus (HCV) the rise in two acy lglycerin acyltransferase and hepatitis c virus core protein in lipid droplets on the surface of the typical position.
●It can protect the heart:
It can reduce blood pressure, enhance capillary resistance, reduce capillary brittleness, reduce blood fat, dilate coronary arteries, increase coronary blood flow and other effects, and also has an adjuvant therapeutic effect on patients with coronary heart disease and hypertension.
●Pure natural quercetin has good effect way to cure cough.
●It is a natural yellow pigment.
