Abstract
目的 建立治糜康栓中苦参碱和氧化苦参碱的含量测定方法,以期更全面地控制治糜康栓的质量.方法 采用(RP-HPLC法)以十八烷基硅烷键合硅胶(C18)色谱柱(4.6 mm×250 mm,5 μm),以乙腈-磷酸盐缓冲液(7 : 93,磷酸二氢钾1.7 g加500 mL纯水溶解,用磷酸调节pH = 3)为流动相,检测波长220 nm,流速1 mL/min,分别对市售治糜康栓与实验室自制治糜康栓中苦参碱及氧化苦参碱的总含量进行测定.结果 市售治糜康栓中苦参碱及氧化苦参碱的总含量约为1.52 mg/粒,实验室自制治糜康栓中苦参碱及氧化苦参碱的总含量约为2.53 mg/粒.结论 建立的反相高效液相色谱方法适用于治糜康栓中苦参碱及氧化苦参碱的含量测定.
