目的建立HPLC测定穿琥宁注射液中的有关物质。方法采用C18柱;以0.05%磷酸二氢钾溶液(用磷酸调PH值至2.5±0.05)-甲醇(3:7)为流动相;检测波长:251nm;流速:1.0ml·min-1。结果样品中均有杂质存在。结论该方法准确、灵敏度高、结果准确。
Objective To establish HPLC determination of Chuanhuning injection related substances. Methods C18 column was used. The mobile phase consisted of 0.05% potassium dihydrogen phosphate solution (pH adjusted to 2.5 ± 0.05 with phosphoric acid) and methanol (3: 7). The detection wavelength was 251 nm and the flow rate was 1.0 ml · min-1. As a result, impurities are present in the sample. Conclusion The method is accurate, sensitive and accurate.
