摘要
目的:本实验旨在探讨利用微波技术辅助提取大花红景天中总黄酮的最佳工艺。方法:以总黄酮含量为指标,通过单因素及正交试验得到微波辅助提取大花红景天中总黄酮的最佳工艺。结果:最佳提取工艺为提取功率200 W,微波时间3 m in,乙醇浓度30%,提取3次,总黄酮含量可达23.47%。结论:该工艺稳定、操作性强,可用于大花红景天中总黄酮的提取。
To research the most effective extraction process of total flavonoids from rhodiola crenulata with microwave technology,the optimal extraction process of total flavonoids was defined by single factor and orthogonal tests with the content of total flavonoids as target.The optimal extraction process was as follows： microwave power of 200W;extracting with microwave for 3min;30% ethanol;totally extracting 3 times.The content of total flavonoids can reach 23.47%.The extraction process of total flavonoids from rhodiola crenulata with microwave technology is stable and operable.
