Quercetin is widely present in angiosperms, such as red tube medicine, cat’s eye grass, iron-covered gold, Manchurian red, loquat leaf, Rhododendron fortunei, Zhaoshanbai, Dwarf tea, Apocynum venetum, this kind of glycoside Yuan, this glycoside is often combined with sugar in the form of glycosides, such as quercetin, rutin, hyperin.
Quercetin is a flavonol compound widely distributed in the plant kingdom and having various biological activities. Quercetin can fight free radicals, complex or trap free radicals to prevent the body’s lipid peroxidation; it can directly inhibit tumors and effectively play anti-cancer and anti-cancer effects; it also has antibacterial, anti-inflammatory, anti-allergic, and prevention of diabetes complications Strong biological activity. In addition, quercetin also has the effects of lowering blood pressure, enhancing capillary resistance, reducing capillary fragility, lowering blood fat, expanding coronary arteries, increasing coronary blood flow, etc. It also has an adjuvant treatment effect on patients with coronary heart disease and hypertension. Quercetin is non-toxic, so it is of great significance for the treatment and prevention of cancer, aging and cardiovascular diseases, and has great development value.
Quercetin is a kind of expectorant commonly used in the clinical practice of Chinese medicine in China. This product has good expectorant and cough suppressing effects, and also has a certain antiasthmatic effect. It also has lower blood pressure, improves capillary resistance, and reduces capillaries. Pharmacological function of fragility, lowering blood fat, dilating coronary artery, increasing coronary blood flow.
Quercetin, as a natural flavonoid compound widely found in nature, has been thoroughly studied, and it has been found to have multiple biological activities, such as antioxidant, antiviral, and anti-inflammatory effects, which can be used in cell and animal experiments Treatment of liver, heart, spleen, lung, kidney, orthopedic diseases, nervous system diseases, etc.
Quercetin is a natural chelating agent that can chelate iron in the body, reduce iron overload in the body, and reduce oxidative damage caused by iron overload.
Quercetin has various effects such as anti-oxidation, scavenging free radicals, inhibiting lipid peroxidation, etc. It can anti-oxidize and protect cardiovascular health, and also shows a good effect in anti-cancer. However, such research data comes from cytology experiments or animal experiments. Whether it works directly in humans still needs more verification.
Summarizing the current research results, it has antioxidant, anti-inflammatory, anti-viral, anti-tumor, hypoglycemic, lipid-lowering, immunomodulatory and other biological activities and a wide range of pharmacological effects. It is effective in treating bacterial infections, viral infections, tumors, diabetes, Hyperlipidemia and immune system diseases have very important clinical significance.
