Preparation method of Quercetin.

Accurately weighed 4.00g of refined rutin (about 2.69mmol) in a 500mL round-bottomed flask, added 400mL of 2% dilute sulfuric acid, and reacted at 80-90°C for 4h, TLC traced to the end of the reaction, left to stand for 4h, and then subjected to reduced-pressure filtration, and the cake was washed to neutrality with distilled water, and dried to obtain the THQ crude product. The resulting crude product was recrystallized with 400 mL of anhydrous ethanol to yield 2.41 g of yellow powder quercetin.
