Objective A HPLC method for determination of relevant materials of atosiban acetate was established.Methods The HPLC system was conducted as follows:Diamonsil C18 column(4.6 mm × 250 mm,5μm);the column temperature was 40℃;mobile phase A:TFA in aqueous 50 mmol/L KH2PO4(pH=3.0):mobile phase B:MeOH:MeCN=60:40;Gradient elution;The injection volume is 20μL;the flow rate was 1.0 mL/min;and the detector wavelength was 220 nm. Results It is known that the peak from the mixed with major peak separation.It had good specificity.Conclusion This method is simple、accurate,and the system applicability is good. It can be used as a atosiban relevant material test methods.
