-----摘要:-------------------------------------------------------------------------------------------
目的:建立测定磷霉素氨丁三醇效价的方法。方法:采用浊度法测定磷霉素氨丁三醇含量,对药典规定的检定菌进行选择,并对微生物浊度法测定磷霉素氨丁三醇效价进行试验设计,结果与管碟法相比较。结果:选择大肠埃希菌为检定菌,浊度法线性范围为12u•mL-1~42u•mL-1,线性方程: Y=-0.7806log(C)+1.5553,r=0.9983。结论:浊度法与管碟法的测定结果无显著性差异,可作为磷霉素氨丁三醇的效价测定方法之一,且更快捷、方便。

To develop a turbidimetric method to determine Fosfomycin Trometamol. Method:Turbidimetric method was used to determine Fosfomycin Trometamol ,compared with diffusion method. Results:The calibration curve was linear in the concentration range of 12 u•mL-1~42 u•mL-1 (r=0.9983) and the average recovery was 99.8% . Conclusion:Turbidimetric method can be used for determining the content of Fosfomycin Trometamol
