The validation was done using concentrations ranging between 75% and 125% of the target concentration of 600 mg/ml. Validation standards were prepared separately in triplicate for each series. Studied validation criteria were selectivity, linearity, trueness, precision (repeatability and intermediate precision), accuracy and limits of detection and quantification. The method was selective, with recoveries ranging between 99.55% and 99.84%. The relative standard deviations of repeatability and intermediate precision were <5%. The accuracy profile confirmed the performance of the assay method between 75% and 100% of the target concentration of 600 mg/ml. The detection and quantification limits were 5 mg/l and 15 mg/l respectively. This ecological and economical method was applied to identify and quantify chlorphenamine maleate in 3 samples of chlorphenamine maleate-based drugs provided by the Senegalese National Medicines Control Laboratory. All analyzed samples were in accordance with official standards.展开更多
目的:采用Waters C18柱(5μm,4.6*250 mm),以磷酸盐缓冲液(取磷酸二氢铵11.5 g,加适量水使其溶解,加磷酸1 m L,用水稀释至1000 m L)-乙腈(80∶20)为流动相。流速1.0 mL/min,检测波长为262,柱温为30℃条件下,建立高效液相色谱(HPLC)测定...目的:采用Waters C18柱(5μm,4.6*250 mm),以磷酸盐缓冲液(取磷酸二氢铵11.5 g,加适量水使其溶解,加磷酸1 m L,用水稀释至1000 m L)-乙腈(80∶20)为流动相。流速1.0 mL/min,检测波长为262,柱温为30℃条件下,建立高效液相色谱(HPLC)测定马来酸氯苯那敏的方法。结果表明,马来酸氯苯那敏的进样量在20.272~141.904μg范围内有良好的线性关系,回归方程y=0.1153x-0.0162(R=0.9999),方法回收率为99.19%~101.68%之间,RSD为0.9%。6批样品的马来酸氯苯那敏含量在98.97%~101.58%之间;结论:此方法专属性强,精密度稳定性良好,准确度较高,可用于该制剂中马来酸氯苯那敏的含量测定。展开更多
