摘要
为探索菊花中总黄酮的最佳提取工艺,采用超声波法对菊花中总黄酮的提取工艺进行了优化,并与醇提法和微波法进行比较。结果表明:超声波法最佳提取工艺条件为:提取时间10m in,料液比1∶20,乙醇浓度80%。超声波法的总黄酮提取率(8.15%)显著高于微波法(5.12%)和醇提法(4.07%)。
Extraction technology of total flavonoid from chrysanthemum by ultrasonic method was optimized and compared with ethanol extraction method and microwave method to explore the optimized extraction technology.Results showed that the optimized extraction technology of ultrasonic method was extraction time 10 min,solid-liquid ratio 1∶20 and ethanol concentration 80%.The extraction efficiency of ultrasonic method（8.15%） was significantly higher than microwave method（5.12%） and ethanol extraction method（4.07%）.
