【摘要】 目的 :应用高效液相色谱法测定复方曲马多片含量。方法 :采用KromasilC18 柱 ,以非那西丁为内标 ,甲醇 -水 -三乙胺(55∶45∶0 2)为流动相 (冰醋酸调pH至4 2) ,检测波长为267nm ,流速0 7ml/min。结果 :曲马多线性范围为50～500μg/ml(r=0.9999 ,n=5) ;奈福泮线性范围为50～500μg/ml(r=0 9999 ,n=5)。曲马多平均回收率为99.69 % ,含量测定结果为100 71 % ,RSD=0.76 % (n=5) ;奈福泮平均回收率为99.76 % ,含量测定结果为99.64 % ,RSD=0.62 % (n=5)。结论 :本方法简便、快速、灵敏 ,结果准确。更多还原

【Abstract】 OBJECTIVE:To establish a HPLC method to determine the content of compound tramadol tablets METHODS:Stationary phase:Kromasil C18 column,internal standard:phenacetin,mobile phase:methanol-water-triethlamine(55∶45∶0 2),adjusting pH to 4 2 with acetic acid,flow rate∶0 7ml/min,detecting wavelength∶267nm RESULTS:The linear range of tramadol (TR) was 50～500μg/ml(r=0 9 999,n=5) The linear range of nefopam(NFP) was 50～500μg/ml(r=0 9 999,n=5) The average recovery of TR was 99 69% The average content of TR was 100 71%,RSD=0 76%(n=5) The average recovery of NFP was 99 76% The average content of NFP was 99 64%,RSD=0 62%(n=5) CONCLUSION:The method is accurate,rapid and simple更多还原
