摘要
目的采用响应面分析法(RSM)优化超声波提取新疆两色金鸡菊中总黄酮的提取条件。方法采用BoxBehnken中心组合设计及RSM分析影响新疆两色金鸡菊中总黄酮的超声波提取条件。结果经RSM数据处理,获得最佳提取条件为:超声提取30 min,液料比21∶1,乙醇浓度60%。在该条件下,新疆两色金鸡菊中总黄酮平均提取率(4.65±0.036)%(n=3)。结论在最佳提取条件下,可从新疆两色金鸡菊中获得质量稳定、含量较高的总黄酮提取物。
Objective Response surface methodology （ RSM ） was applied to optimize the ultrasonic extraction conditions for flavonoids from Coreopsis tinctoria Nutt. Methods The influence factors of ultrasonic extraction were evaluated using the Box-Behnken central component experiments and analyzed by RSM. Results The optimum extraction conditions were confirmed as follows：extraction time 30. 0 min, ratio of liquid to solid 21∶1, concentration of ethanol 60%. The yield of flavonoids under this condition was （4.65±0.036）% （n=3）. Conclusion The flavonoids could be extracted with stability and higher yield from Coreopsis tinctoria Nutt under optimized conditions.
