Abstract:
Objective: To optimize of ultrasonic-assisted extraction technology of total flavonoids from
Bambusae caulis in taenias based on response surface methodology. Method: On the basis of single-factor experiment, four parameters including ethanol concentration, solid-liquid ratio, ultrasonic power and ultrasonic time were selected as influencing factors and the optimum conditions for total flavonoids extract were obtained through Box-Behnken center united experiment designed by response surface methodology. Results: The optimum conditions were as follows; the ethanol concentration was 67%; the solid-liquid ratio was 1:25; the ultrasonic power was 330 W and the ultrasonic time was 26 min. Under the conditions, the extraction rate of total flavonoids could be reached to 3.557%. Conclusion: This method is simple, rapid and reliable which could provide reference for the producing of total flavonoids from
Bambusae caulis in taenias.
