Abstract
The optimum ultrasonic extraction conditions of polyphenols in celery leaves were obtained by single-factor experiment as follows:ethanol solution content of 85%,the ratio of material to liquid of 0.8g/10mL,the extracting time of 50min and the extracting temperature of 40℃.The content of polyphenol in celery leaves was determined as 30mg/g by spectrophotometry.
