Quercitrin


Quercitrin is a glycoside formed from the flavonoid quercetin and the deoxy sugar rhamnose.
Austrian chemist Heinrich Hlasiwetz is remembered for his chemical analysis of quercitrin.
It has also been investigated as a potential dietary supplement.

Occurrence

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

Metabolism

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