高效液相色谱法测定甲苯磺酸妥舒沙星片的含量 石文宏朱庆玲 (内蒙古食品药品检验所呼和浩特 010010 ) 摘要目的:建立甲苯磺酸妥舒沙星片含量测定的高效液相色谱法,方法:采用高效液相色谱法,C18柱(250×,5μm),()-乙腈(73:27),流速:,检测波长:270nm。结果:甲苯磺酸妥舒沙星在5~60ug/ml范围内与峰面积呈良好的线性关系(r =),%,%。结论:高效液相色谱法简便、灵敏、准确、重现性好,可用于测定甲苯磺酸妥舒沙星片含量。 关键词甲苯磺酸妥舒沙星片;高效液相色谱法;含量测定 ABSTRACT:OBJECTIVE To establish a HPLC method for concurrent determination of tab Tosufloxacin toluene sulfonate. METHODS The HPLC system consisted DiamonsilTM C18 column (×250mm,5µm), Citric acid(Triethylamine pH )-Acetonitrile (73:27) as mobile phase with detection wave Length at 270nm,flow rate was -1. , temprature of column was 25℃. RESULTS The linear range of Tosufloxacin toluene sulfonate were within5~60µg·mL-1 ,the average recorvery was %(RSD=%). CONCLUSION The established method was suitable for the concurrent determination of Tosufloxacin toluene sulfonate. The method was convenient and accurate.
