【摘要】 目的:建立测定奥硝唑凝胶中主药含量的方法。方法:采用一阶导数光谱法,在259nm和299nm波长处测定凝胶中奥硝唑的含量。结果:奥硝唑线性范围为4.01～44.1μg.mL-1,平均回收率为101.6%(RSD=1.3%)。结论:本方法精密度、准确度均能满足奥硝唑凝胶质量控制要求。更多还原

【Abstract】 OBJECTIVE:To establish a method for determining the content of Ornidazole gel by first-order derivative spectrophotometry.METHODS:The first-order derivative spectrophotometry was used to determine the content of Ornidazole gel at a wavelength of 259nm and 299nm.RESULTS:The linear range of Ornidazole was 4.01～44.1μg·mL-1.The average recovery was 101.6%,with RSD of 1.3%.CONCLUSIONS:This method can meet the requirements for quality control of Ornidazole gel both in terms of precision and accuracy.更多还原
