Abstract：In order to improve the extraction rate of total flavonoids from Sanghuangporus lonicericola,this study used the fruiting body of S.lonicericola as the raw material,and used ultrasound assisted ethanol extraction to extract its total flavonoids.The extraction process was optimized by response surface testing,which was conducted based on single factor tests of liquid-solid ratio,ethanol concentration,ultrasonic time,and ultrasonic temperature.The optimal extraction process of total flavonoids from the fruit bodies of S.lonicericola was as follows:solid-liquid ratio of 1∶60,ethanol concentration of 60％,ultrasonic time of 60 min and ultrasonic temperature of 76 ℃.In the optimal conditions,the extraction rate of total flavonoids from S.lonicericola was 0.80％,which was close to the predicted value of 0.83％of the model,indicating that the optimized process is reasonable and feasible,can improve the extraction rate of total flavonoids from S.lonicericola,and facilitate the deep processing of S.lonicericola products and the comprehensive utilization of Sanghuang resources.
