摘 要 目的:建立超高效液相色谱法(UPLC)法测定注射用特利加压素中有关物质的含量。方法:采用UPLC法测定5批注射用
特利加压素制剂中有关物质的含量。色谱柱为Xtimate UPLC C18,流动相A为硫酸铵缓冲液(pH 2.3)-甲醇(90∶10,V/V),流动相B
为硫酸铵缓冲液(pH 2.3)-甲醇(60∶40,V/V),梯度洗脱,流速为0.2 mL/min,检测波长为210 nm,进样量为5 μL。结果:注射用特利
加压素中杂质A、B、C、D、F、H、I、K、L、N 的检测质量浓度线性范围为0.43~3.86、0.44~3.95、0.44~3.97、0.45~4.08、0.45~4.05、
0.50~4.50、0.47~4.26、0.47~4.23、0.46~4.13、0.44~3.96 μg/mL(r≥0.999 7);检测限分别为 0.04、0.04、0.05、0.04、0.05、0.05、
0.05、0.05、0.04 μg/mL,定量限分别为 0.13、0.13、0.14、0.13、0.15、0.14、0.14、0.14、0.13 μg/mL;精密度、重复性、稳定性试验的 RSD

ABSTRACT OBJECTIVE:To establish UPLC method for the content determination of related substances in Terlipressin for
injection. METHODS:UPLC method was used to determine the contents of related substances in 5 batches of Terlipressin for
injection. The separation was performed on Xtimate UPLC C18 column with mobile phase A consisted of ammonium sulfate buffer
(pH 2.3)-methanol(90 ∶ 10,V/V)and mobile phase B consisted of ammonium sulfate buffer(pH 2.3)-methanol(60 ∶ 40,V/V)
(gradient elution) at the flow rate of 0.2 mL/min. The detection wavelength was set at 210 nm,and sample size was 5 μ L.
RESULTS:The linear range of impurity A,B,C,D,F,H,I,K,L and N were 0.43-3.86,0.44-3.95,0.44-3.97,0.45-4.08,
0.45-4.05,0.50-4.50,0.47-4.26,0.47-4.23,0.46-4.13,0.44-3.96 μg/mL(r≥0.999 7),respectively. The detection limits were 0.04,
0.04,0.05,0.04,0.05,0.05,0.05,0.05,0.04 μg/mL. The quantitation limits were 0.13,0.13,0.14,0.13,0.15,0.14,0.14,
0.14,0.13 μ g/mL,respectively. RSDs of precision,reproducibility and stability tests were all lower than 8% . The average
recoveries were 94.95%,97.81%,101.88%,95.26%,93.40%,102.48%,104.26%,102.31%,96.42%,90.42%,with RSDs
of 1.89%,1.86%,0.68%,1.30%,1.98%,3.36%,1.26%,1.30%,1.19%,1.40%(n=9),respectively. Total contents of
impurities in 5 batches of Terlipressin for injection were all lower than 4%. CONCLUSIONS:Established method is rapid,simple,
accurate and specific,which can be used for the quantitative analysis for related substances in Terlipressin for injection.
