Optimization of extraction condition to pigment from cherry blossoms by ultrasonics

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.
