| | QUERCITRIN Usage And Synthesis |
| Chemical Properties | Yellow solid | | Uses | antiinflammatory, antioxidant, antihemmorrhagic | | Uses | Quercitrin has been used as textile dye. Flavine yellow shade is prepared by extracting quercitron bark with high pressure steam and consists mainly of quercitrin: Tisdale, Can. Text. J. 57, 44 (1941).
| | Uses | Quercitrin is known as an bio flavonoid antioxidant and was investigated extensively in its antioxidant potential in streptrozotocin (STZ)-induced diabetic rats. Quercitrin is also a constituent of th e dye quercitron. Quercitrin can be found in Tartary buckwheat and in oaks species such as white oak or European red oak.
