Rutin, also called rutoside, quercetin-3-O-rutinoside and sophorin, is the glycoside combining the flavonol quercetin and the disaccharide rutinose (α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranose). It is a citrus flavonoid found in a wide variety of plants including citrus fruit.
Occurrences
Rutin is one of the phenolic compounds found in the invasive plant species Carpobrotus edulis and contributes to the antibacterial[3] properties of the plant.
Its name comes from the name of Ruta graveolens, a plant that also contains rutin.
Metabolism
The enzyme quercitrinase can be found in Aspergillus flavus.[4] It is an enzyme in the rutin catabolic pathway.[5]
In food
Rutin is a citrus flavonoid glycoside found in many plants including buckwheat,[6] the leaves and petioles of Rheum species, and asparagus. Tartary buckwheat seeds have been found to contain more rutin (about 0.8–1.7% dry weight) than common buckwheat seeds (0.01% dry weight).[6] Rutin is one of the primary flavonols found in 'clingstone' peaches.[7] It is also found in green tea infusions.[8]

Research
Rutin (rutoside or rutinoside)[10] and other dietary flavonols are under preliminary clinical research for their potential biological effects, such as in reducing post-thrombotic syndrome, venous insufficiency, or endothelial dysfunction, but there was no high-quality evidence for their safe and effective uses as of 2016.[10][11][12] As a flavonol among similar flavonoids, rutin has low bioavailability due to poor absorption, high metabolism, and rapid excretion that collectively make its potential for use as a therapeutic agent limited.[10]
