摘 要: 目的:建立不同基源与不同产地葛花药材在形态学、显微鉴定学、理化性质等方面的鉴别方法。方法:采用数码摄影技术从形态学区分粉葛花与野葛花;采用偏光显微镜建立粉葛花与野葛花粉末显微鉴别特征;采用薄层色谱(thin layer chromatography,TLC)实验分析粉葛花与野葛花的化学特征性成分及含量差异。结果:野葛花与粉葛花在形态学、显微鉴定学、TLC谱图中均存在一定的差异。结论:以上鉴别方法准确可靠,重复性好,为野葛花和粉葛花药材建立科学可靠的质量标准提供实验依据。
关 键 词: 中药学;鉴别;显微鉴定;薄层色谱;葛花

Abstract: Objective: To establish the identification methods of morphology, microscopy, physical and chemical properties of Pueraiae flos crude drugs from different radical sources and different origin areas. Methods: Digital photography technology was applied to distinguish P. lobata flos and P. thomsonii flos from morphology. Microscopic features of P. lobata flos and P. thomsonii flos were established using polarizing microscope. The differences between P. lobata flos and P. thomsonii flos in chemical characteristic components and their contents were investigated by thin layer chromatography (TLC) experiments. Results: The differences in morphology, microscopic identification and TLC map were existed between P. lobata flos and P. thomsonii flos. Conclusion: The method was reliable and repeatable, and it could provide experimental basis for establishing scientific and reliable quality standard.
Key words: traditional Chinese pharmacology; idenfification; microscopic identification; thin layer chromatography; Puerariae flos
