摘　　要： 研究了超声强化提取葵粕绿原酸中主要参数-乙醇浓度、液料比、超声功率、超声辐照方式、超声提取时间以及超声提取次数等-对绿原酸萃取率的影响。通过在单因素实验基础上进行的三因素三水平的Box-Behnken实验,得到了优化的工艺条件:在乙醇浓度为70%、辐照方式占空比9s:6s、超声提取30min的条件下,液料比为27.3ml/g,超声功率为200W,提取3次,绿原酸的萃取率可达到98.87%。 Effect of factors such as ethanol concentration, ratio of solvent to sample, ultrasound power, mode of ultrasound irradiation, extraction duration and operation times on extraction yield of chlorogenic acid has been investigated. On the basis of experimental results of single factor, experimental design of Box-Behnken is carried out and optimum extraction conditions are obtained Extraction yield of chlorogenic acid reaches 98.87% under the following conditions： using ethanol of 70% concertration, 30 minutes of ultrasound irradiation with 9s/6s of on/off ratio, 27.3ml/g of solvent to sample ratio, 200W ultrasound power, and of 3 times.
