HPLC 测定盐酸罂粟碱原料药中的有关物质

    Determination of the Related Substances in Papaverine Hydrochloride Active Pharmaceutical Ingredients by HPLC

    • 摘要:
      目的 建立HPLC检测盐酸罂粟碱原料药中有关物质的方法。
      方法 采用NanoChrom ChromCore 120 C8色谱柱,以磷酸二氢钾溶液(3.4 g·L−1磷酸二氢钾水溶液,磷酸调pH至3.5)-乙腈(90∶10)作为流动相A ,甲醇为流动相B,梯度洗脱,流速 0.8 mL·min−1,检测波长 238 nm,柱温50 ℃。
      结果 主成分与各杂质间最小分离度>1.5;主成分以及其13个杂质在各自的浓度范围内呈良好的线性关系 (r>0.999);平均回收率为93.1%~101.2%,RSD为 2.3%~8.1%。
      结论 本方法准确、灵敏、可靠,适用于盐酸罂粟碱原料药有关物质的测定。

       

      Abstract:
      OBJECTIVE  To establish an HPLC method for determination of the related substances in papaverine hydrochloride.
      METHODS  NanoChrom ChromCore 120 C8 column was used; the mobile phase A consisted of 3.4 g·L−1 potassium dihydrogen phosphate aqueous solution, adjust pH to 3.5 with phosphoric acid-acetonitrile(90∶10), the mobile phase B was methanol, with gradient elution at the flow rate of 0.8 mL·min−1; the detection wavelength was 238 nm; the column temperature was 50 ℃.
      RESULTS  The minimum separation between the main component and each impurity was >1.5; Papaverine and its thirteen impurities showed a good linear relationship in the self-concentration range(r>0.999); and the average recoveries were 93.1%−101.2% with RSDs of 2.3%−8.1%.
      CONCLUSION  The method is accurate, sensitive and reliable, which is suitable for the determination of related substances in papaverine hydrochloride.
