摘要
以金银花为原料,采用微波超声双辅助提取绿原酸。通过单因素实验对乙醇浓度、超声温度、超声时间、料液比、微波功率、微波时间等工艺参数进行研究,并通过响应面法优化提取工艺,建立二次多项数学模型。结果表明,单因素和响应面优化金银花绿原酸的最优工艺参数为:微波功率400W、微波时间94s、液料比42∶1mL/g、乙醇浓度70%、超声温度为60℃、超声时间60min,此条件下金银花绿原酸提取率为5.45%。
The microwave-ultrasonic-assisted extraction of chlorogenic acid from Flos Lonicerae was optimized using response surface methodology. The extraction yield of chlorogenic acid was investigated with respect to six process parameters including ethanol concentration ,temperature, ultrasonic treatment time, solvent-to-solid ratio,microwave power and microwave time. As a result,a quadratic polynomial mathematical model was built. The optimal extraction conditions of RSM were determined as follows：Flos Lonicerae were suspended in microwave power of 400W,microwaves 94s,70% ethanol concentration at solvent-to-solid ratio 42：1mL/g and then subjected to ultrasonic treatment for 60min at temperature of 60℃. Under the modified conditions,the extraction yield of polvohenols was 5.45%.
