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.
Rutin, also called rutoside, is the glycoside flavonoid found in a certain fruits and vegetables. Most rutine-rich foods are capers, olives, buckwheat (whole grain flour), asparagus, raspberry.In a clinical trial, rutin was found to aid control of intraocular pressure in patients with primary open angle glaucoma. As a component of dietary supplement Phlogenzym, rutin is used for treatment of osteoarthritis. Rutin is also used for treatment of post-surgical swelling of the arm after breast cancer surgery. Traditionally, rutin is used to prevent mucositis due to cancer treatment, to treat blood vessel disease such as varicose veins, bleeding, hemorrhoids.
Its name comes from the name of Ruta graveolens, a plant that also contains rutin.
Citrus leaves contain rutin at concentrations of 11 and 7 g/kg in orange and lime trees respectively.
Rutin is a citrus flavonoid glycoside found in many plants including buckwheat, 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). Rutin is one of the primary flavonols found in ‘clingstone’ peaches. It is also found in green tea infusions.

Rutin (rutoside or rutinoside) 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.[needs update] 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.
The biosynthesis pathway of rutin in mulberry (Morus alba L.) leaves begins with phenylalanine, which produces cinnamic acid under the action of phenylalanine ammonia lyase (PAL). Cinnamic acid is catalyzed by cinnamic acid-4-hydroxylase (C4H) and 4-coumarate-CoA ligase (4CL) to form p–coumaroyl-CoA. Subsequently, chalcone synthase (CHS) catalyzes the condensation of p-coumaroyl-CoA and three molecules of malonyl-CoA to produce naringenin chalcone, which is eventually converted into naringenin flavanone with the participation of chalcone isomerase (CHI). With the action of flavanone 3-hydroxylas (F3H), dihydrokaempferol (DHK) is generated. DHK can be further hydroxylated by flavonoid 3´-hydroxylase (F3’H) to produce dihydroquercetin (DHQ), which is then catalyzed by flavonol synthase (FLS) to form quercetin. After quercetin is catalyzed by UDP-glucose flavonoid 3-O-glucosyltransferase (UFGT) to form isoquercitrin, finally, the formation of rutin from isoquercitrin is catalyzed by flavonoid 3-O-glucoside L-rhamnosyltransferase.
The compound 2 was synthesized for the first time by highly selective esterification reaction and fully characterized. The by-products of the reaction were complex, which brought out many considerable difficulties in separation and purification of the target product. Our work was the first in using the improved pyrogallol autoxidation method to test the antioxidant activities of these two flavonoids compounds in vitro and discovered that the compound 2 was much more effective as a free radical scavenger than the compound 1.
Synthesis of Rutin
The synthesis of rutin can be achieved according to the following three schemes. These schemes differ in the synthesis of ouercetin (the aglycone moiety of rutin).
Scheme 1: Kostanecki — et al. 1904 (33 ). Based upon the Claisen reaction between 2-hydroxy4, 6-dimethoxyacetophenone [l] and 3, 4-dimethoxybenzaldehyde  to give the intermediate  which upon treatment with HC1, cyclization occurs to give 5, 7, 3 , which upon treatment with F2SO4 enolisation occurs to give 5, 7, 1’3 ,’4 -tetramethoxyflavonol . tion with HI affords quercetin .
Scheme 2: Robinson et al. 1926 (34 ). , ‘4 -tetramethoxyflavonone . Oximination affords  Demethyla- — Condensation ofw-methoxypholoroacetophenone [I] with veratric acid anhydride  in the presence of the potassium salt of veratric acid to give the diarylester . On hydrolysis with alcoholic KOH affords 5, 7-dihydroxy-3, /3 , ‘4 -trimethoxyf lavone [ 41 , which on demethylation with HI gives quercetin .
Scheme 3: Shakhova et al. 1962 (35), complete synthesis of rutin. W-methoxyphloroacetophenone  was condensed with 0-benzylvanillinic acid, anhydride [ 13 in triethylamine to give 5 , 7-dihydroxy-4 -benzyloxy-3, /3 -dimethoxyf lavone . On treatment with AcOH-HC1 mixture gave 5, 7, ‘4 -trihydroxy-3,’3 -dimethoxyflavone . Demethylation of the latter with HI yielded (about 802) quercetin . Ouercetin potassium salt  was produced upon treating  with AcOK in ethanol. Levoglucosan  was acetylated with Ac20 in the presence of AcONa to give 2, 3, 4-triacetyllevoglucosan  which with TIC14 gave 1-chloro-2, 3, 4-triacetyl Dglucose . L-rhamnose tetraacetate [lo] treated with TiBr4 in CHC13 gave 1-bromo-2, 3, I-triacetyl-L-rhamnose [ll]. [lo] +  heated with Hg (OAC)~ in C6H6 gave (53x) CC – acetochloro-f3-l-L-rhamnosido-6-D-glucose .  was treated with AgOAc and acetylated with Ac20 to prodilce (68.703 B-heptaacet yl-f3-1-L-rhamnos ido-6-D-glucose . This with 33% HBr in AcOH gave (61%) d – acetobromo-~-l-L-rhamnosido-6-D-glucose .  and quercetin potassium salt  were dissolved in NH40H which was evaporated and treated with methanol andpurified over a chromatographic column packed with polycaprolactum resin to give rutin [151.
