高效液相色谱法测定阴泰洗液中替硝唑的含量

Determination of Tinidazole in Yintai Cleaning Solution by HPLC

目的 :建立测定阴泰洗液中替硝唑含量的高效液相色谱方法。方法 :以Nova-PakC18 为色谱柱 ,甲醇 -水 -冰醋酸 (22∶78∶0.1)为流动相 ,甲硝唑为内标 ,检测波长为310nm。结果 :替硝唑在20～100μg/ml浓度范围内线性关系良好 (r=0 9999) ;平均回收率为101.2 % (n=5) ,RSD=1 22 %。结论 :本方法简便、快速 ,测定结果准确 ,重现性好。

OBJECTIVE:To establish a HPLC method for determining the content of tinidazole in Yintal cleaning soluˉtion.METHODS:Nova-Pak C 18 column was used.The mobile phase was methanol-water-glacial acetic acid(22∶78∶0.1). Internal standard was metronidazole.The UV detection wavelength was310nm.RESULTS:There was a good linerarity within the concentration range of20～100μg/ml of tinidazole in Yintai solution(r=0.9999).The average recovery was101.2%(n=5,RSD=1.16%).CONCLUSION:This method is simple,fast and accurate.
