| Abstract: | The amount of fluorine in pazufloxacin mesilate medicine was determined by ^19F-NMR technology with sodium trifluoroacetate as an internal standards and the mixture of deutoxide and deionized water as solvent. The experimental conditions were optimized. The average recoveries are in the range of 99.2%-100.9% with the standard deviation of 0. 00446%-0. 0652% and the relative standard deviation less than 1. 459%. |
