Quercetin, also known as quercetin or quercetin, was discovered by the Hungarian physiologist Szent Gyorgyi in 1936. The melting point is 314ºC. It is soluble in ethanol,glacial acetic acid, etc., but insoluble in water, benzene, ether, etc. The alkaline aqueous solution is yellow and almost insoluble in water, with a bitter taste. It has antioxidant properties and can be used as a medicine. It has a good expectorant and antitussive effect and also has a certain anti-asthmatic effect. In addition, it has the functions of lowering blood pressure, enhancing the resistance of capillaries, reducing the fragility of capillaries, lowering blood lipids, dilating coronary arteries, and increasing coronary blood flow. It is used for the treatment of chronic bronchitis and also has an auxiliary therapeutic effect on patients with coronary heart disease and hypertension.
