摘 要:目的:优选镰形棘豆总黄酮的提取工艺。方法:以总黄酮含量为指标,在单因素试验的基础上,采用星点设计-效应面法考察溶剂用量、乙醇体积分数、提取时间对镰形棘豆总黄酮含量的影响。结果:最佳提取工艺为加入20倍量66%乙醇回流提取2次,每次84 min,在此条件下,总黄酮的含量达23.21 mg·g^(-1)。结论:采用星点设计-效应面法优选的提取工艺条件稳定可行,预测性好。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.
