祛湿止痒洗液薄层色谱鉴别研究

Study on TLC Identification of Dehumidification and Antipruritic Lotion

摘要: 目的：建立祛湿止痒洗剂的薄层色谱鉴别(TLC)方法。方法：采用TLC法对祛湿止痒洗液中马齿苋、苦参、和地榆进行定性鉴别。结果：马齿苋、苦参和地榆薄层色谱斑点清晰，阴性对照无干扰，不同型号色谱板均能较好地鉴别出几种药材。结论：本试验所用方法简单、准确性高、重复性好，可用于祛湿止痒洗剂的薄层鉴别质量控制。

Abstract: Objective: To establish a TLC method for the identification of dehumidification and antipruritic lotion. Methods: Purslane, Sophora flavescens and Sanguisorba officinalis in dehumidification and antipruritic lotion were qualitatively identified by TLC. Results: The TLC spots of Purslane, Sophora flavescens and Sanguisorba officinalis were clear, and the negative control had no interference. Different types of chromatographic plates could better identify several medicinal materials. Conclusion: The method used in this test is simple, accurate and repeatable, and can be used for the TLC identification and quality control of dehumidification and antipruritic lotion.
