【摘要】 目的建立操作简便、专属性强的大黄中土大黄苷检查方法。方法通过对比聚酰胺、硅胶薄层色谱法(TLC)和高效液相色谱法(HPLC)检测大黄药材中的土大黄苷的研究,考察鉴别正、伪品大黄的最佳方法。结果采用聚酰胺、硅胶TLC方法检查大黄中土大黄苷的耐用性较差,HPLC更适用于土大黄苷的检测。结论本研究确定的HPLC方法准确可靠,可用于大黄药材的质量控制,为药典用大黄的真伪鉴别提供参考。更多还原

【Abstract】 Objective To establish a simple and specific method for the determination of rhaponticin in Rhei Radix et Rhizoma. Methods A comparison of the methods of polyamide, silica gel TLC and HPLC in the determination of rhaponticin was studied to investigate the optimum way to identify authentic Rhei Radix et Rhizoma. Results The durability of polyamide and silica gel TLC method for the determination of rhaponticin in Rhei Radix et Rhizoma was poor. HPLC method was more suitable for the detection of rhaponticin. Conclusion HPLC method is accurate and reliable, and can be used for the quality control of Rhei Radix et Rhizoma and provide references for the authenticity of Rhei Radix et Rhizoma.更多还原
