RUTOSIDE (rutin)

DescriptionRutin 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.

HistoryIn the mid-1930s, Hungarian scientist Szent Gyorgy firstly separated the flavonoid mixture. After the German pharmacy firstly made it into ranosine in 1942, the concept of vitamin P has been established worldwide. Further study proved that rutin was the most important flavonoids of vitamin P. These compounds were certified to have effects on many diseases in medical.Recently, the research of rutin mainly focuses on the extraction process improvement, pharmacological effects, and pharmacodynamics research, aiming at improvement of its bioavailability through the development of different dosage forms. As for the extraction process, new extraction and purification methods have been developed since the original alkali extraction acid precipitation method. These methods greatly improve its extraction efficiency and reduce cost, including hot water precipitation, hot water extraction with macroporous resin adsorbing purification, ultrasonic radiation, hot water extraction with alcohol precipitation, cold alkali percolation extraction with acid precipitation, continuous reflux extraction, ethanol extraction, supercritical CO2 extraction, and enzymatic hydrolysis .In recent years, advanced rutin dosage forms, such as rutin cyclodextrin saturation, HPMC controlled release tablets, solid dispersion tablets, coprecipitate, and rutin effervescent particles, greatly improve the rutin dissolution rate and its bioavailability.

UsesFound in many plants, especially the buckwheat plant. Identity with Ilixanthin. Capillary protectant. Rutin is colored brown by tobacco enzyme under experimental conditions.

Usesantidiabetic, dipeptidyl peptidase–4 inhibitor
