摘 要 目的:研究青梅感冒冲剂中岗梅、甘草的薄层色谱鉴别方法。方法：分别取甘草药材、岗梅药材、青梅感冒冲剂及阴性制剂的乙酸乙酯提取液，在硅胶板上前者以ψ(苯∶乙酸乙酯∶水)=5∶2∶0.1展开，后者以ψ(甲苯∶乙酸乙酯∶水)=5∶2∶0.1展开，在紫外灯(365 nm下)检视。结果：在两者供试品色谱中与各自对照药材色谱相应位置上，均有相同的特征斑点，阴性制剂色谱图中无此斑点。结论：该法专属性强，为该制剂增加质量控制指标提供了实验依据。关键词 青梅感冒冲剂；岗梅；甘草；薄层色谱法

Abstract To study the TLC identification of liquorice(radix glycyrrhizae) (RG) and ilex asprella (IA) in QinMei Cold Granule. Methods: The extracts of RG, IA and its preparation were subjected to TLC in different development systems. ψ(Benzene∶acetic ether∶water)=5∶2∶0.1 and ψ(toluene∶ acetic ether∶water)=6∶2∶0.1 were used as development reagents for RG and IA respectively. Results: Special spots could be observed at 365 nm on positions corresponding to RG, IA and the preparation respectively, while the negative control showed no spots.Conclusion:This method is highly exclusive and can be used in the quality control of the preparation. ......
