| Abstract: | Objective:to establish ,the optimal conditions for ultrasonic extraction of total flavonoids from Mulberry leaves.Methods:The conditions for the extraction were studied by the orthogonal experimental design as guided by the content of total flavonoids in the extract.Results:a significant effect,the time of ultrasonic extraction,was observed. Conclusion:Using total flavonoids as a detecting index,the optimum conditions are that the concentration of alcohol is 50 %,the rate of solvent to raw materials is 20 times and the ultrasonic time is 30 min. |
