The red pigment was extracted from Begonia fimbristipula Hance with ethanol by the ultrasonic method. The ultrasonic extraction ethanol concentration,temperature,time,solid to liquid ratio were stud-ied. The result showed that the optimal conditions were as follows:ethanol concentration 20%,50 ℃ and 80 min,solid to liquid ratio of 1∶13(g/mL),the extraction rate was 10. 04% under this condition.
