For quality control of medicines, it is necessary to establish an appropriate separation method in the analysis of specific ingredient. A tablet containing trimethoprim, sulfamethazine, enrofloxacin, apramycin and oxytetracycline as an antibiotics were used. Assay and identification tests were made and compared with the standard of each material by the HPLC. Materials separated and purified with HPLC were then characterized by 1H-NMR, 13C-NMR, DEPT, COSY, TOCSY and HSQC NMR spectroscopy. Experimental HPLC conditions for antibiotics were independently set up and compared with those of standard samples. In addition, the purity identifications of each sample are accomplished by the complete NMR signal assignments.
