Abstract: Objective To establish a HPLC method for determination of related substances of risedronate sodium tablets. Methods The C18 column,5 μm,150 mm×4.6 mm,the buffer solution (3.22 g tetrabutyl ammonium bromide was added to a buffer solution of 1 000 ml 0.05 mol/L ammonium chloride,then adjusted pH to 7.8±0.05 by ammonia)-methanol-acetonitrile =250:50:25 as mobile phase,column temperature:room temperature,flow rate:1.0 ml/min,detection length:254 nm. Results Determined by HPLC at high temperature,acid,alkali degradation,the main peak and the impurity peaks were separated well,and the peaks had a linear relationship,Y=1.28×107X-1.62×105 (r=0.999 9). Conclusion The method was rapid,simple,accurate and sensitive,and suitable for determination of risedronate sodium tablets related substances.
