Objective To optimize the extracting technology of total falconoids from Ixeris chinensis （Thunb.） Nakai by ultrasonic wave. Methods The contents of total falconoids were served as indicating index, and the effects of solid-liquid ratio, ethanol concentration, extraction time and temperature on total falconoids were studied by ultrasonic extraction. Result The optimal ultrasonic condition was as follows： the feed-liquid rate was 1：50; the ethanol concentration was 70%, the ultrasonic temperature was 45 ~C and the ultrasonic time was 50 min. Conclusion The extraction of total falconoids from I. chinensis by ultrasonic wave was found to be a rapid and efficient extraction method with short time and high production yield, it can be applied to the extraction of total falconoids of I. chinensis
