Abstract: | Objective: To establish a turbidimetric method for determination the content of Midecamycin tablets. Method: The test organism was Staphylococcus aureus , adjusted spore suspension of Staphylococcus aureus inoculating with a 1.2% -2.5 % (V/V)ratio, cultivated at(37 ± 0.5 )℃ for about 4 -5h. Result: The liner range of midecamycin was 1.0 -3.0 IU-ml^-1 (r = 0.991 0). The average recovery of Midecamycin tablets was 102.1% ( RSD = 2.1%, n = 9). Conclusion : The method is sensitive , rapid and feasible to determine the potency of Midecamycin tablets. |
