Template:Chembox Footer/trackingTemplate:Short description
Quercitrin is a glycoside formed from the flavonoid quercetin and the deoxy sugar rhamnose.
Austrian chemist Heinrich Hlasiwetz (1825-1875) is remembered for his chemical analysis of quercitrin.
It has also been investigated as a potential dietary supplement.[1]
Occurrence
Quercitrin is a constituent of the dye quercitron. It can be found in Tartary buckwheat (Fagopyrum tataricum)[2] and in oaks species like the North American white oak (Quercus alba) and English oak (Quercus robur).[3] It is also found in Nymphaea odorata or Taxillus kaempferi.[4]
Metabolism
The enzyme quercitrinase catalyzes the chemical reaction between quercitrin and H2O to yield L-rhamnose and quercetin.
