Objective: To optimize extraction technology of total flavonoids from Baeckea frutescens L. Method: With the content of total flavonoids as index
ethanol concentration
solid-liquid ratio and extraction time as factors
central composite design and response surface methodology was used for optimize of extraction technology of total flavonoids from B. frutescens L.
then predicted optimal exaction process. Result: Optimum extraction technology conditions were as follows:extracted 3 times with 16 times the amount of 70% ethanol
60 min each time.Under this technology
the average mass fraction of total flavonoids was 1.43%. Conclusion: The observed value and the predicted value were close
which proved that optimizied technology was reasonable and feasible with good predictability.
