Abstract:
Objective: To optimize the extraction process of total flavonoids from Oxytropis falcata bunge.Methods: With the content of total flavonoids as the index,and based on the results of single factor tests, central composite design-response surface methodology was adopted to optimize the extraction technology with the solvent amount, ethanol concentration and extraction time as the factors.Results: The optimal extraction conditions were as follows: extracted twice with 20-fold amount of 66% ethanol, and 84 minute per time.Under the above conditions, the extraction rate of total flavonoids was up to 23.21 mg·g-1.Conclusion: The central composite design-response surface methodology is convenient and highly predictive for the extraction optimization of total flavonoids from oxytropis falcata bunge.
