Thin-layer identification method for pharbitis seed sample

The invention relates to a thin-layer identification method for a pharbitis seed sample. The thin-layer identification method comprises the following steps: preparing a test solution, preparing a reference medicinal material solution and a reference substance solution, and carrying out thin-layer identification. A test solution, a reference medicinal material solution and a reference substance solution are obtained by adopting a simple, convenient and rapid pretreatment method, are respectively dripped on the same thin-layer plate, and are developed by using a suitable developing solvent to obtain a multi-information morning glory seed thin-layer chromatogram. The method is simple, convenient and rapid to operate, good in chromatographic spot separation degree, low in detection cost, safe, environment-friendly and more beneficial to quality supervision of the semen pharbitidis sample. 本发明涉及一种牵牛子样品的薄层鉴别方法，包括供试品溶液制备、对照药材溶液和对照品溶液制备、薄层鉴别步骤。本发明采用简便、快捷的前处理方法得到供试品溶液、对照药材溶液与对照品溶液，分别点于同一块薄层板上，用适宜展开剂展开，得到多信息的牵牛子薄层色谱图。该
