摘　　要：目的 :测定复方氟罗沙星栓及复方氟罗沙星滴耳液中2组分含量。方法 :采用联立方程组新解法不经分离直接测定复方氟罗沙星栓及复方氟罗沙星滴耳液中氟罗沙星、替硝唑及氟罗沙星、甲硝唑的含量。结果 :以286、317nm分别为复方氟罗沙星栓中2组分的测定波长 ,以蒸馏水为空白 ,氟罗沙星和替硝唑的平均回收率及RSD分别为100 17 %、0 44 %和99 96 %、0 37 % ;以286、318nm分别为复方氟罗沙星滴耳液中2组分的测定波长 ,以蒸馏水为空白 ,氟罗沙星和甲硝唑的平均回收率及RSD分别为100 65 %、0 65 %和99 92 %、0 21 %。结论 :本法操作简便快速 ,重现性好 ,可消除各处方中2组分的相互干扰 。OBJECTIVE:To establish a New Vierordt method for assaying ingredients in compound fleroxacin suppositories and compound fleroxacin ear drops METHODS:New Vierordt method was applied to determination of fleroxacin and tinidazole in compound fleroxacin suppositories and fleroxacin and metronidazole in compound fleroxacin ear drops with no need of separation RESULTS:The fleroxacin and tinidazole in compound fleroxacin suppositories were detected at wavelength 286nm and 317nm respectively The average recoveries were 100 17% and 99 96% with RSDs=0 44% and 0 37% respectively The fleroxacin and metronidazole in the compound fleroxacin ear drops were detected at wavelength 286nm and 318nm respectively The average recoueries were 100 65% and 99 92% with RSDs=0 65% and 0 21% respectively CONCLUSION:The New Vierordt method can be used for quality control of the two compound preparations because of its convenience,accuracy and good repeatability and can eliminate mutual interference of two ingredients in preparations
