Quercetin:3,3',4',5,7-Pentahydroxyflavone dihydrate:Introduction and Its Benefit Applications.

Quercetin Discovery Story.

Quercetin:3,3',4',5,7-Pentahydroxyflavone dihydrate CAS:6151-25-3 EINECS ELINCS No.:204-187-1 Chem IUPAC Name:2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxychromen-4-one bioflavonoid anti-tumour photo picture image Quercetanus (1607) was one of the first mediaeval scientists to recognise the existence of the essential oil industry for lavender and juniper oils leading to the discovery of another group - the terpenes.

Quercetin (3,3',4',5-7-pentahydroxyflavone), a chemical cousin of the glycoside rutin, is a unique flavonoid that has been extensively studied by researchers around the world, starting with the discovery of both vitamin C and flavonoids by Albert Szent-Gyorgyi who received the Nobel Price in 1937 for research in this area. Flavonoids, by the way, are plant polyphenolics found as the pigments in leaves, barks, rinds, seeds, and flowers-frequently closely associated with Vitamin C and offering synergistic effects. Both flavonoids and Vitamin C benefit plants by providing them with antioxidant protection and also confer protection against climatic variations (in wind, rainfall, temperature, and sunlight). Flavonoids are also important for human health. Like vitamins, these compounds are not produced endogenously by the body and must be supplied either through the diet or nutritional supplements.

Quercetin has been the subject of dozens of scientific reports over the past 30 years. It has shown the greatest activity among the flavonoids studied in experimental models. Quercetin is frequently used therapeutically in allergic conditions, including asthma and hayfever, eczema, and hives. Additional clinical uses include treatment of gout, pancreatitis and prostatitis, which are also, in part, inflammatory conditions. The common link is its ability to mediate production and manufacture of pro-inflammatory compounds.
