| Abstract: | Objective：To optimize the supersonic extracting process for total flavonoids from lotus leaf.Methods：The extracting rate of rutin was used as evaluated index in orthogonal test.Effects of ethanol concentration,supersonic extraction time,ultrasonic power and solid to liquid ratio on the extraction rate of total flavonoids were studied.Results：The optimal conditions for ultrasonic extraction of total flavonoids were as follows：60% of ethanol extracted for 40 min at 250 W with the material to liquid ratio of 20∶1.Conclusion：This process is simple and stable for the extraction of total flavonoids from lotus leaf. |
