Sophora japonica extract(98% Quercetin)

Quercetin (3,3′,4′,5,7-pentahydroxyflavone) is a naturally occurring flavonoid belonging to the flavonol subclass.

It is one of the most abundant and widely distributed dietary flavonoids, found in a variety of plant sources including onions, apples, berries, citrus fruits, buckwheat, and green tea.

It is also present in significant quantities in Sophora japonica (Japanese pagoda tree) and Ginkgo biloba, which are common commercial sources for extract standardization.

Quercetin is characterized by its potent antioxidant capacity and its ability to modulate multiple signaling pathways involved in inflammation, cellular proliferation, and metabolism.

Its molecular structure features five hydroxyl groups, which confer strong free radical scavenging activity and metal chelation properties.

It is often referred to as one of the most active and versatile flavonoids in the plant kingdom.

These properties have made quercetin one of the most extensively studied flavonoids, with applications spanning immune support, cardiovascular health, metabolic function, and healthy aging.
