Method: 1. The TLC identification of baicalin. 2. Using bupleurum medicinal materials as contrast medicinal materials to select suitable method and solvent extraction and identification of bupleurum saponins. 3. The identification of saikoside of bupleurum in sustained release table. Result: the color of the text solution shows the same color sports at the corresponding position where the color of the control medicine is. When having viewed the saikosaponin a and d under the 365nm ultraviolet, the author found that saikosaponin a has on fluorescence and saikosoponin d has fluorescence. Conclusion: in this paper, the author used the method of separation of using ultrasonic extraction, which not only can make the required component be dissolved, but also excess the complex water-soluble component, and control the quality of Bupleurum returd tablets better. Key words: TLC ; Bupleurum tenue sustained-release tablets; saikosoponin; Baicalin.  目 录 前言 1 1材料与仪器 1 1.1 材料和仪器 1 2实验方法与结果 2 2.1黄芩苷的TLC鉴别 2 2.1.1 黄芩苷对照品溶液的制备 2 2.1.2 供试品溶液的制备 2 2.1.3．阴性对照溶液的制备： 3 2.1.4．薄层色谱法试验 3 2.2柴胡皂苷的TLC鉴别 3 2.2.1有效成分提取方法的考察 3 2.2.2小柴胡缓释片中柴胡皂苷的鉴别 5 3讨论 6 参考文献 7 致谢 8 前言 小柴胡汤主要成分为柴胡、黄芩、党参等七味中药，其中柴胡为君药、黄芩为臣药, 其主要活性成份为柴胡皂苷和黄芩苷[1-3]，小柴胡汤具有解表散热、疏肝和
