Abstract: | Objective: To optimize a method for the determination of peptide content in cerebroprotein hydrolysate tablets.Methods: A size-exclusion chromatography method and an HPLC method were used for the identiifcation of peptide and the determination of peptide content in cerebroprotein hydrolysate tablets, respectively.Results: The result of size-exclusion chromatography method had the advantages of high speciifcity. The standard curve of every amino acid was linear (r>0.999) with average recovery 98.0%~102.4%.Conclusion: This method is simple, accurate, sensitive and reproducible, and can be applied in the quality control of cerebroprotein hydrolysate tablets. |
