Product Introduction:
Quercetin, also known as quercetin, is a widely distributed flavonoid alcohol compound with various biological activities in the plant kingdom, with the chemical formula C15H10O7.

Quercetin is widely found in the stem bark, flowers, leaves, buds, seeds and fruits of many plants, mostly in the form of glycosides, such as rutin, quercitrin, hyperoside, etc. Quercetin can be obtained by acid hydrolysis. Among them, the content is higher in the stems and leaves of buckwheat, seabuckthorn, hawthorn, and onion. Quercetin is also found in many foods, such as onions, shallots, asparagus, cabbage, mustard, green peppers, chicory, grapefruit, lettuce, hawthorn, apples, mangoes, plums, radishes, black currants, potatoes, and spinach. In addition, more than 100 medicinal plants (such as Sophora japonica, Platycladus orientalis leaves, Alpinia officinalis, Lonicera japonica, Morus parasiticus, Panax notoginseng, Ginkgo biloba, Elderberry, etc.) contain this ingredient.

[Physical properties]: Dihydrate is a yellow acicular crystal (dilute ethanol) that becomes anhydrous at 95-97 ° C, with a melting point of 314 ° C (decomposition). 1g is soluble in 290ml of anhydrous ethanol, 23ml of boiling ethanol, and in glacial acetic acid. The alkaline aqueous solution is yellow and almost insoluble in water. The ethanol solution has a bitter taste.


Product Advantage:
This product has good expectorant and antitussive effects, as well as certain antiasthmatic effects. In addition, it has the effects of reducing blood pressure, enhancing capillary resistance, reducing capillary fragility, lowering blood lipids, expanding coronary arteries, and increasing coronary blood flow.

Product Function:
1. Antioxidation
Quercetin is a strong antioxidant in nature, with an antioxidant capacity 50 times that of vitamin E and 20 times that of vitamin C. Studies have shown that quercetin has a good scavenging effect on superoxide anion, hydroxyl radical, and singlet oxygen, and there is a significant dose effect relationship.
2. Anti inflammatory effect
Quercetin can regulate NF- κ B. Suppress TNF- α The production and gene expression of inflammatory mediators, as well as the expression of inflammatory mediator genes, thereby reducing the release of inflammatory mediators. The antioxidant effect of quercetin also helps reduce inflammatory reactions.
