The study compared the effect of ultrasonic method, microwave extraction and ethanol extraction process of total flavonoids from Radix Astragali. The ultrasonic extraction method works best. The extraction method was optimized by orthogonal test with the content of total flavonoids of Radix Astragall as index and with the ultrasonic extraction temperature, extraction time, solid-fluid ratio, the volume fraction of ethanol as the investigated factors. The results showed that the optimum conditions were as follows.ultrasonic wave temperature 65 ;C, ultrasonic wave time 30 min, material to ratio of liquid 1 : 15 ,volume fraction of ethanol 65; ,Comparison with the initial results,the extraction rate can reach up to 0.418 %, 1.31 times of the microwave extraction, 1.69 times of ethanol extraction.
