摘要
目的 :建立提取白芷中香豆素类成分的方法。方法 :以欧前胡素为指标 ,用薄层色谱法对提取香豆素类成分所用的溶剂种类、极性和提取方式进行系统研究。结果 :用 4倍量 95 %乙醇回流提取 2次 (每次 1h)的方法提取白芷中的香豆素类有效成分可以获得较高提取效率。结论 :溶剂种类和提取方式对白芷中欧前胡素的提取效率有较大影响。
Objective: To build an extraction method of coumarins from Radix Angelicae Dahuricae. Methods: The solvent varieties, polarities, and extraction methods were systematically studied by TLC with imperatorin as marker.Results: The more effective way to extract coumarins from Radix Angelicae Dahurica was refluent extraction with 4 times amount of 95% alcohol twice (one hour each time).Conclusion: The Solvent varieties and extraction method showed greater effects than others on the extraction efficiency of imperatorin.
