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

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
