摘 要:目的建立测定苯磺顺阿曲库铵中有关物质的高效液相色谱法。方法采用高效液相色谱-二极管阵列检测器法。流动相梯度洗脱,流动相A为1.02%磷酸二氢钾缓冲溶液(用磷酸调节p H至3.1)-甲醇-乙腈(75∶5∶20),流动相B为1.02%磷酸二氢钾缓冲溶液(用磷酸调节p H至3.1)-甲醇-乙腈(50∶30∶20);色谱柱为Thermo Syncronis C18柱(250 mm×4.6 mm,5μm),流量为1.0 m L/min,柱温为30℃,进样体积为20μL,检测波长为280 nm。结果苯磺顺阿曲库铵质量浓度线性范围为0.005~1.0 g/L(r=0.999 9),检测限为5 ng/m L(S/N≥3);杂质E、杂质G、中间体Ⅻ和中间体ⅩⅢ的质量浓度线性范围分别为0.8~40.0μg/m L,1.2~60.0μg/m L,40~200μg/m L,1.6~80.0μg/m L(r≥0.999 8),检测限分别为40 ng/m L,30 ng/m L,100 ng/m L,80 ng/m L(S/N≥3)。结论该法检测苯磺顺阿曲库铵的有关物质,灵敏度高、专属性强,结果准确可靠。Objective To establish a HPLC method for the determination of related substances in cisatracurium besilate. Methods HPLC-diode array detector(DAD) was adopted. The mobile phase was performed the gradient elution. The mobile phase A was 1.02% potassium dihydrogen phosphate buffer solution (adjusting to pH 3.1 with phosphoric acid)-methanol-acetontrile (75:5:20) and the mobile phase B was 1.02% potassium dihydrogen phosphate buffer solution(adjusting to pH 3. 1 with phosphoric acid)-methanol- acetontrile (50:30:20). The separation of analyte was performed on a Thermo Syncronis Cls column(250 mmx4.6 mm,5μm). The flow rate was 1.0 mL/min,the column temperature was set at 30 ℃ and the injection volume was 20μL. DAD was set at 280 nm. Results The linear range of cisatracurium besilate was 0. 005- 1.0 g/L(r =0. 999 9),the minimum detection limit was 5 ng/mL(S/ N≥3);the linear ranges of mass concentrations for impurity E and G,midbody Ⅻ andⅫ were 0. 8-40. 0 μg/mL, 1.2-60.0 μg/mL, 40 - 200 μg/mL and 1.6 - 80. 0 μg/mL( r≥ 0. 999 8), and the minimum detection limits were 40,30,100,80 ng/mL( S/ N≥3 ). Conclusion This method for determining the related substances in cisatracurium besilate is strongly specific, highly sensitive, accurate and reliable in the detection results.
