Abstract

Objective To establish a method to determinate scopolamine hydrobromide injection by ion pair RP-HPLC.Methods The mobile phase of methanol-20mmol/L sodium heptanesulfonate solution acetic acid (50:50:2) and ZORBAX SB-C₁₈ column (4.6×250mm,5μm)was used,the flow rate was 0.9mL/min and the detect wavelength was 225nm.Results The linear range of scopolaminc hydrobromide was 0.1～0.5mg/mL(r=0.9999). The average recovery was 100.15%,RSD was 1.58%.Conclusion The method was simple,rapid and accurate. It can be used to control the quality of scopolamine hydrobromide injection.
