Rutin (Rutoside) is a flavonoid found in many plants and shows a wide range of biological activities including anti-inflammatory, antidiabetic, antioxidant, neuroprotective, nephroprotective, hepatoprotective and reducing Aβ oligomer activities. Rutin can cross the blood brain barrier. Rutin attenuates vancomycin-induced renal tubular cell apoptosis via suppression of apoptosis, mitochondrial dysfunction, and oxidative stress.

Rutin is widely found in nature and is almost contained in all of the Rutaceae and Sectaceae plants, especially abundant in Rutaceae, Rutaceae, Epacridaceae of leguminous, buckwheat of Polygonaceae, Eulali of Hypericum, Berchemia polyphylla var. leioclada of Tetranychidae, and wild wutong leaves of thistle, which are also used as raw materials in rutin extraction. In addition, it also exists in the Ilex pubescens of Aquifoliaceae, Forsythia of Oleaceae, pagoda tree pod of Leguminosae, tobacco, jujube, apricots, flavedo, tomatoes, and other plants.
At present, rutin in China mainly extracted from the Sophora japonica Linn of leguminous, which is listed in top grade of Shen Nong’s Classic Materia Medica. In addition, tartary buckwheat, which is rich in rutin and flavonoids, is native to India and now produced in China’s northwest, southwest, north, south, and other places.

Rutin is mainly used for the adjuvant treatment of hypertension and treatment for the prevention of other bleedings due to lack of rutin, such as cerebral hemorrhage, retinal hemorrhage, purpura, acute hemorrhagic nephritis, chronic bronchitis, and abnormal blood osmolality, restoration of capillary elastic embolism, and also for the prevention and treatment of diabetes and hyperlipidemia . Troxerutin, the most important active ingredient in hydroxy rutin, is used in the treatment of varicose veins/venous disorders, hemorrhoids, lymphedema, and postoperative edema, treatment of thrombosis and cerebrovascular disease, and also in the treatment of diabetes and liver disease. Since rutin has a mild effect with low cost and less adverse reactions, especially its remarkable effect on acute cerebral infarction, it is of great worth on promotion and application of rutin .
