.The total flavonoids in Herba Artemisiae Scopariae was extracted by microwave assistant or ultrasonic assistant using 70% ethanol as extracting solvent.The influences of extracting time,rate of material to liquid,microwave power or ultrasonic power on extracting rate were investigated and the technology conditions were optimized by orthogonal.The results show that the optimal extracting conditions for ultrasonic assistant extraction are as follows: extracting time,temperature,rate of material to liquid and...
