摘要
目的：研究白车轴草中黄酮类化合物的离子液体-超声辅助提取的最佳工艺。方法：以白车轴草中黄酮类含量为指标,使用单因素和正交实验优化黄酮的提取工艺。结果：离子液体-超声辅助提取白车轴草中黄酮的最佳工艺为：白车轴草粉末加入0.25 mol/L的1-丁基-3-甲基咪唑四氟硼酸盐[BMIM][BF4]、提取90 min,料液比为25 mg/mL。结论：离子液体-超声辅助提取法提取白车轴草中黄酮稳定、可行。
Objective：To study the best technology of extraction flavonoids from White clover by ionic liquids based ultrasonic assisted extraction method. Methods：The flavonoids content in white clover were as indicators. By using the single factor and orthogonal experiment,we optimized the extraction process of flavonoids. Results：The best technology of extraction flavonoids from White clover by ionic liquids based ultrasonic assisted extraction is the extraction solvent of 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4]with the concentration of 0. 25 mol/L,extraction time 90 min and solvent to solid ratio 25 mg/mL.Conclusion：By using ionic liquids based ultrasonic assisted extraction method,we extract flavonoids from White clover stably and feasibly.
