摘要
目的 :建立乳酸环丙沙星滴眼液含量的测定方法。方法 :采用双波长分光光度法 ,以0.1mol/L盐酸为稀释液 ,检测波长为237nm和279nm。结果 :乳酸环丙沙星浓度在3～9μg/ml范围内有良好的线性关系 ,r=0.9998 ;平均回收率为101 6 %,RSD为2 16 %。结论 :本法简便快捷、定量准确 ,可作为乳酸环丙沙星滴眼液的含量测定方法。
OBJECTIVE:Dual-wavelength spectrophotometry was developed for the determination of ciprofloxacin lactate in its eye drops.METHODS:Detection was performed at wavelength 237nm and 279nm with 0.1mol/L HCl as diluent.RESU_LTS:The assay was linear for ciprofloxacin lactate in the concentration range of 3～9μg/ml,r=0.9 998;The mean recovery was 101.6%,RSD was 2.16%.CONCLUSION:This method is simple,quick,accurate and suitable for the determination of ciprofloxacin lactate in its eye drops.
