Objective: To optimize the ultrasound-assisted extraction technology of total flavonoids from Sedum sarmentosum Bunge. Method: The factors such as ethanol concentration, liquid-material ratio and extraction temperature were optimized by response surface methodology. Result: The highest extraction rate of total flavonoids by ultrasound-assisted extraction could arrive at 21.7 mg?g-1 using 60 % ethanol concentration, liquid-material ratio of 26∶1, extraction temperature 60 ℃, and extraction time 20 min, which was agreed with model predictions. Conclusion: The extraction process by ultrasound-assisted was stable and reliable.
