Aperçu
Quercetin, chemically known as 3,3',4',5,7-pentahydroxyflavone, has the molecular formula C15H10O7 and CAS number 117–39–5. Quercetin est un naturelly occurring flavonoid compound widely found in nature, belonging to the vitamin P group. It is extensively present in the stems, bark, flowers, leaves, buds, seeds, and fruits of many plants. Common quercetin-rich plant sources include Sophora japonica buds (Huaimi), ginkgo biloba leaves, onions, apples, green tea, and buckwheat. Quercetin appears as a yellow crystalline poudre, odorless with a slightly bitter taste. Quercetin itself contient two molecules of bound water (dihydrate), and the content determination requires calculation based on anhydrous quercetin. As one of the most widely distributed and most extensively studied flavonoid compounds in nature, quercetin is renowned for its potent antioxydant, anti-inflammatory, and immunomodulatory activities, with broad applications in dietary supplements, functional foods, pharmaceuticals, and cosmetics. Quercetin has a clear regulatory status and testing standards in Chine. GB 5009.248–2016 "National aliment Sécurité norme – Determination of Quercetin in aliments" specifies the method for determining quercetin content in foods. The "National aliment Sécurité norme – Additif Alimentaire – Quercetin" specifies the quality requirements, testing methods, and label identification for quercetin (including quercitrin). It should be noted that according to domestic regulatory requirements, quercetin is not yet included in the food catalog and cannot yet be used or sold as a food ingredient in Chine.
