Quercetin is a natural flavonoid. Its chemical name is 3,3', 4', 5,7-pentahydroxyflavone. Quercetin mainly exists in the flower, leaf and fruit of plants in the form of glycosides, such as rutin (rutin), quercetin, hyperin and so on. Many Chinese herbal medicines, such as Sophora japonica, jujube, Apocynum venetum, mulberry leaf, ginkgo leaf, notoginseng, buckwheat and so on, contain this ingredient. The content of Sophora japonica flower is as high as 4%. Quercetin has many biological activities, such as anti-tumor, anti-inflammatory, anti-oxidation, anti-platelet aggregation and free radical scavenging.


  Chemopreventive effect on tumors  

Quercetin has a chemopreventive effect on tumors through its complex role in cell proliferation and angiogenesis-related signaling pathways.

  Antidiabetic effect of Quercetin  

Quercetin has a strong inhibitory effect on aldose reductase in diabetic kidney. Early application can prevent or delay the occurrence of diabetes mellitus.

  Cardiovascular protection of Quercetin  

Quercetin has pharmacological activities such as vasodilating, lowering blood pressure, lowering blood lipid, lowering capillary permeability and fragility, and preventing and treating coronary heart disease.

  Antidiarrheal effect of Quercetin  

When intestinal infections occur, the intestinal tract is stimulated by pathogenic microorganisms and toxins. The secretion of acetylcholine, a chemical inflammatory mediator, increases. The cholinergic receptor acting on the intestinal tract accelerates intestinal peristalsis. The retention of nutrients and electrolytes in water and food in the intestinal tract is shortened, resulting in diarrhea. Quercetin can inhibit the release of acetylcholine from isolated ileum of guinea pigs, inhibit the contraction of ileum induced by acetylcholine, and inhibit the intestinal propulsion function and the permeability of abdominal capillaries.
