Rutin (from Japanese sophora bud)
Rutin is a flavonol glycoside comprised of quercetin and rutinose. An antioxidant,1,2 rutin is found in many foods, especially buckwheat, black tea, apple peels, onions and citrus fruits.3
The flower buds of the Japanese sophora or pagoda tree, Sophora japonica, are a rich source of the bioflavonoid rutin. The buds have been used for centuries in Chinese cultures, and the tree is often used in bonsai horticulture.4
