目的对小儿氨酚黄那敏颗粒中人工牛黄的鉴别方法进行研究。方法采用硅胶G薄层板,分别以异辛烷-乙酸丁酯-冰醋酸-甲酸(8∶10∶5∶1)为展开剂,制定了人工牛黄中的胆酸、猪去氧胆酸的薄层色谱鉴别。结果色谱斑点清晰,重现性好。结论该方法操作简便,专属性强。 Objective To study the identification method of artificial bezoar in children’s aminophenol Huangnamin granules. Methods Using silica gel G thin-layer plates, using iso-octane-butyl acetate-glacial acetic acid-formic acid (8:10:5:1) as the developing agent, the bile acid and hyodeoxycholic acid in artificial bezoar were thinned out. Layer chromatography identification. As a result, the chromatographic spots were clear and the reproducibility was good Conclusion This method is simple and specific.
