摘要
目的 :用荧光分光光度法测定洛美沙星注射液及胶囊中洛美沙星的含量。方法 :样品稀释后 ,以285nm为激发波长 ,445nm,为发射波长 ,荧光分光光度法测定其含量。结果 :洛美沙星在0 5～2 5μg/ml浓度范围呈现良好的线性关系 ,回归方程为 :Y=19 64C—0 34 ,r=0 9998。注射液及胶囊回收率分别为99 7 %(RSD=0 6 %,n=5)和99 6 %(RSD=0 8 %,n=5)。结论 :本法简便易行、灵敏度高、重现性好 ,可用于洛美沙星注射液及胶囊的含量测定。
OBJECTIVE:A fluorospectrophotometric method was established for the determination of lomefoxacin hydrochloride in injection and capsule.METHODS:Samples were diluted with distilled water and detected by fluorospectrophotometry at excitation wavelength of 285nm and emission wavelength of 445nm.RESULTS:Linear relationship was found in the lomefloxacin hydrochloride concentrations ranging from 0.5μg/ml to 2.5μg/ml.The correlation coefficient was 0.9 998.The recoveries of lomefloxacin in injection and capsule were 99.7%(RSD=0.6%,n=5) and 99.6%(RSD=0.8%,n=5),respectively.CONCLUSION:The method is simple,accurate and sensitive and can be used to determine lomefloxacin hydrochloride in injection and capsule.
