注射用肌氨肽苷中多肽的含量测定方法研究

Study on the Method to Assay Peptide Concentration of Muscular Amino Acids and Nucleosides

目的:建立注射用肌氨肽苷中多肽的含量测定方法。方法:用福林-酚法测定多肽含量。结果:三批样品多肽含量均在85.0%～115.0%之间。结论:用国家药品标准肌氨肽苷注射液规定的福林酚法检测多肽,可用于本品质量标准的研究。

Objective：To establish a method to assay peptide content of Muscular amino acids and nucleosides. Methods：Applying Folin - phenol Reagent Method to assay peptide concentration. Results：The cooncentration of peptide is between 85.0% - 115.0% among the three batch samples respectively. Conclusion：Applying Folin -phenol Reagent Method to assay peptide could be used to study the quality standard of Muscular amino acids and nucleosides
