摘要
目的:采用超声波辅助技术提高大火草中黄酮提取率。方法:采用单因素和正交实验法,以大火草总黄酮提取率为指标,确定最佳提取工艺条件。结果:最佳提取工艺条件为:乙醇浓度60%、料液比1∶50、超声功率90W、超声时间80min、提取3次,在该工艺条件下,总黄酮提取率为1.474%。结论:该提取工艺简单可行,适用于大火草总黄酮的提取。
Objective：The experiment adopted ultrasonic-assisted technology to improve extraction rate of total flavonoids from Anemone tomentosa.Methods：On the base of the single factor test and orthogonal experiment,in order to obtain the optional technology conditions of extraction rate of flavonoids.Results：The optimal technology conditions were as follows：The concentration of ethanol was 60%,solid liquid ratio was 1∶50,power of ultrasonic instrument 90W,extraction for 80min,extracting times was 3.The extraction rate of flavonoids from Anemone tomentosa was 1.474% under the optimal extraction technology.Conclusion：The optimum process was reasonable and feasible.
