摘要
本试验采用超声波辅助溶剂提取法提取了柳蒿芽总多酚,通过单因素实验探究了料液比、乙醇浓度、超声时间、超声功率这四个因素对总多酚得率的影响,并利用正交试验优化确定了柳蒿芽总多酚得最佳提取条件。结果表明:在料液比(mg/L)1∶30,乙醇浓度80%、超声时间30 min、超声功率300 W条件下,总酚得率最大为5.247%,该提取工艺操作简便,安全可靠。
In this experiment, ultrasonic assisted solvent extraction method was used to extract the total polyphenols from artemisia integrifolia L., and the single factor experiment was used to explore the influence of the ratio of material to liquid, ethanol concentration, ultrasonic time, and ultrasonic power on the total polyphenol yield, and the orthogonal experiment was used to optimize the extraction conditions of total polyphenols from Artemisia Integrifolia L. The results showed that the maximum yield of total phenol was 5.247 mg/g under the conditions of material liquid ratio 1∶30 mg/L, ethanol concentration 80%, ultrasonic time 30min and ultrasonic power 300 W. The extraction process was simple, safe and reliable.
