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.

Quercitrin is a constituent of the dye quercitron. It can be found in Tartary buckwheat (Fagopyrum tataricum) and in oaks species like the North American white oak (Quercus alba) and English oak (Quercus robur). It is also found in Nymphaea odorata or Taxillus kaempferi.

The enzyme quercitrinase catalyzes the chemical reaction between quercitrin and H₂O to yield L-rhamnose and quercetin.
