RP—HPLC法分离科素亚片中芦沙坦钾有关物质及含量测定

Isolation of Related Compounds and Determination of Losartan Potassium in COZAAR Tablets by RP-HPLC

  • 摘要: 采用反相高效液相色谱法,分离科素亚(COZAAR) 片中有关物质,并定量测定芦沙坦钾(Losartanpotassium) 含量,色谱条件为:ZORBAX CN 色谱柱(15 cm ×4 .6 m m ) ,乙腈0 .01 mol/L 磷酸氢二钾(50∶50 ,pH2 .5) 为流动相,检测波长为230 nm 。芦沙坦钾在15 ~35 μg/ml 浓度范围内呈良好的线性关系,回归方程为:y =43306 x 9758( r= 0 .9999) ,平均回收率为99-5 % ( n = 5 ,RSD= 1 .1 % ) 。
