目的:研究克痛药膜中的元胡、血竭、姜黄、大黄4味中药的薄层色谱。方法:采用薄层色谱法,在硅胶G薄层板上,以环己烷-丙酮(8∶2)为展开剂,鉴别元胡;以石油醚(60～90℃)-乙醚(3∶2)为展开剂,鉴别大黄;以三氯甲烷-甲醇-甲酸(96∶4∶0.7)为展开剂为展开剂,鉴别姜黄;以三氯甲烷-甲醇(19∶1)为展开剂,鉴别血竭。结果:依据正文所述方法,薄层展开后,色谱斑点显色清晰,分离效果好,与对照药材显色一致。结论:依据正文所述方法,针对元胡、血竭、姜黄、大黄4味中药,其薄层色谱图的检出成分消除了其它成分的干扰,专属性强,重现性好,方法简便,可以作为该制剂质量控制的检测标准。
Objective: To study the thin layer chromatogram of the Chinese herbal medicine of Yuanhu, Zuogui, Tuhuang, Rhubarb in Keke film. Methods: Thin layer chromatography (TLC) was used to identify Yuanhu with cyclohexane - acetone (8: 2) ) For the development of agents to identify rhubarb; chloroform - methanol - formic acid (96: 4: 0.7) as the developing agent for the development of agents to identify turmeric; chloroform - methanol (19: 1) exhaust. Results: According to the method described in the text, after the thin layer was unfolded, the chromatographic spots showed a clear color and the separation effect was good, which was consistent with that of the control medicine. Conclusion: According to the method described in the text, the detection components of Yuan-hu, Xue-fu, Turmeric and rhubarb were all detected by TLC, which eliminated the interference of other components. The specificity, reproducibility and method were simple, Can be used as the quality control of the preparation of the test.
