Abstract： Using Tremella aurantialba as raw material， microwave assisted extraction of total flavonoids from Tremella aurantialba was used， and the optimal extraction process of total flavonoids from Tremella aurantialba was determined through single factor experiments and response surface analysis. The results showed that the optimal extraction process for total flavonoids from Tremella aurantialba was material to liquid ratio 1∶20 （mg∶mL）， microwave time 4 minutes， microwave power 400 W， and ethanol concentration 60%. Under these experimental conditions， the microwave extraction rate of total flavonoids from Tremella aurantialba was 0.671 2%.
