| 摘 要： | 建立了磷酸替米考星可溶性粉中替米考星含量的HPLC测定方法。采用高效液相色谱(HPLC)法,使用十八烷基硅烷键合硅胶为填充剂的色谱柱,以水∶乙腈∶磷酸二丁胺缓冲液∶四氢呋喃(805∶115∶25∶55)为流动相,流速1.0 mL/min,检测波长280 nm,柱温25℃。按外标法以峰面积计算含量。在此色谱条件下,替米考星顺式、反式异构体峰分离度良好,磷酸替米考星可溶性粉的线性范围为0.2~0.8 mg/mL(R 2=0.9998),平均回收率为97.96%,RSD<1.0%。本研究建立的方法分离效果好、精密度高、稳定性好,可作为磷酸替米考星可溶性粉的质量关键控制指标。

| Abstract: | To establish a HPLC method for the determination in tilmicosin phosphate soluble powder,HPLC was used for the column with octadecyl silane bonded silica gel as the filler,and the mobile phase was determined with water∶acetonitrile∶dibutylamine phosphate solution∶tetrahydrofuran(805∶115∶25∶55);The flow rate was 1.0 mL/min,the detection wavelength was 280 nm,and the column temperature was 25℃calculating content by peak area according to external standard method.Results showed that under these chromatographic conditions,the separation of cis-and trans-isomers was satisfactory.The linear range of tilmicosin phosphate soluble powder was 0.2~0.8 mg/mL,R 2=0.9998.The average recovery was 97.96%,RSD<1.0%.The method established in this study has good separation effect,high precision and good stability,and can be used as a key quality control index for the tilmicosin phosphate soluble powder. |
