摘要
目的优选超声提取法从桑枝中提取总黄酮的工艺条件。方法以分光光度法测定桑枝总黄酮,采用正交试验法对桑枝总黄酮超声提取工艺进行研究。结果最佳工艺条件为:乙醇浓度80%,料液比1∶8,超声提取3次,每次提取时间20min。结论超声提取法是一种简单、快捷、高效的提取桑枝黄酮的方法。
Objective To optimize the ultrasonic extraction technology of flavonoids from Ramulus Mori. Methods Ultrasonic extraction technology was optimized by orthogonal test, and the content of total flavonoids was determined by spectrophotometry. Results The optimal condition was： extracting for 3 times and 20 min for each time, with 8 fold of 80% ethanol. Conclusion The ultrasonic extraction technology was simple, rapid and high efficient.
