Uses and synthesis of Quercetin powder

Quercetin powder is a common plant secondary metabolite known chemically as 3,3',4',5, 7-pentahydroxy flavonoids. Quercetin is a yellow crystalline powder that is almost insoluble in water at room temperature and soluble in organic solvents such as ethanol and dimethyl sulfoxide. It has strong antioxidant properties that can stabilize free radicals and protect cells from free radical damage. Quercetin is a kind of expectorant commonly used in Chinese traditional medicine clinic.

2. Quercetin has good expectorant, antitussive and antiasthmatic effects. It is used in the treatment of chronic bronchitis, and also has auxiliary therapeutic effect on patients with coronary heart disease and hypertension

Physicochemical Property of Quercetin powder

Yellow acicular crystalline powder. Thermally stable, decomposition temperature 314℃. It can improve the light resistance of food pigments and prevent the change of food flavor. It changes color when exposed to metal ions. Slightly soluble in water, easily soluble in alkaline aqueous solution.

Production methodprocess of Quercetin powder

The bark of Quercus plants in the beech family is ground into powder, washed in hot salt water, extracted with dilute ammonia, and neutralized with dilute sulfuric acid. The filtrate is boiled and crystallized to produce Quercetin powder.
