Abstract
With cherry blossoms as the raw material to extract pigment, optimized experimental conditions which affect the extraction rate, including ethanol concentration, extractant acidity, extraction times, liquid-solid ratio, ultrasonic time and ultrasonic power.The best condition of pigment extraction was got.Results showed that the optimum conditions were pH =1 with 60% ethanol, liquid-solid ratio 20:1, in the 400W power ultrasonic extraction under 30min for three times.
