        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.
