Ultrasonic extraction of natural red pigment from pitaya skin was optimized by the single factor experiment method. The effects of ultrasonic treatment power, ultrasonic treatment time, temperature, pH value and ratio of liquor to material on the extraction yield were investigated. The optimized ultrasonic extraction was determined as follows:the extraction temperature 30℃, extraction pH value 4.0, the ratio of liquor to material 8 mL/g at 300 W for 15 min with 50 % ethanol in a single ultrasonic extraction process. A comparison was conducted between ultrasonic and the ethanol refluxing extraction. The results showed that the extraction yield of red pigment by ultrasonic extraction was higher than it of the ethanol refluxing extraction , ultrasonic extraction was faster and needed less solvent, which were superior to solvent extraction method.
