La description

Présentation du produit

98% Poudre de quercétine is a pure natural plant ingredient extracted from pagoda tree (Sophora Japonica) flower buds, the best natural source for quercetin. We use advanced purification and crystallization technology to keep the quercetin content steadily at 98%. This product features fine texture, high purity, few impurities and good solubility. Known as the “King of Flavonoids”, quercetin is a widely used natural ingredient for daily health foods, nutritional supplements and skin care products.

What Is Quercetin?

Quercetin is a natural active substance found in many plants. Pagoda tree flower buds contain the highest content and best quality natural quercetin. Its chemical formula is C15H10O7, with CAS numbers: 117-39-5 (Anhydre) / 6151-25-3 (Dihydraté).
Different from common plant extracts, our quercetin is made through strict processes: raw material selection, low-temperature extraction, impurity filtering and fine purification. This process removes useless plant fiber and impurities, and retains pure and active quercetin ingredients. With stable quality and good activity, it is a high-quality raw material for daily health care and skin care products.
