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.{{cite journal| author=Audah KA, Ettin J, Darmadi J, Azizah NN, Anisa AS, Hermawan TDF | display-authors=etal| title=Indonesian Mangrove Sonneratia caseolaris Leaves Ethanol Extract Is a Potential Super Antioxidant and Anti Methicillin-Resistant Staphylococcus aureus Drug. | journal=Molecules | year= 2022 | volume= 27 | issue= 23 | page=8369| pmid=36500458 | doi=10.3390/molecules27238369 | doi-access=free| pmc=9735687 }}
