Rutin

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.

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.

Various citrus fruit peels contain 32 to 49 mg/g of flavonoids expressed as rutin equivalents.[4]

Citrus leaves contain rutin at concentrations of 11 and 7 g/kg in orange and lime trees respectively.[5]

Metabolism

The enzyme quercitrinase can be found in Aspergillus flavus.[6] It is an enzyme in the rutin catabolic pathway.[7]

In food

Rutin is a citrus flavonoid glycoside found in many plants including buckwheat,[8] 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).[8] Rutin is one of the primary flavonols found in 'clingstone' peaches.[9] It is also found in green tea infusions.[10]

Research

Rutin (rutoside or rutinoside)[12] 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 2018.[12][13][14] 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.[12]
