摘    要:目的:建立浊度法测定麦迪霉素片剂含量的方法。方法:以金黄色葡萄球菌为试验菌,加菌量为1.2%~2.5%(V/V),(37±0.5)℃培养4~5h左右测定。结果:麦迪霉素线性浓度为1.0~3.0IU·ml^-1,r=0.9910,平均回收率为102.1%,RSD为2.1%(n=9)。结论:本方法灵敏,快速,影响因素较少,可作为测定麦迪霉素片剂效价的方法。

关 键 词:效价  浊度法  麦迪霉素  麦迪霉素片

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.
Keywords:Potency  Turbidimetric method  Midecamycin  Midecamycin tablets
