Objective: To select suitable oligopeptide assay method. Methods: Determination of oligopeptide for the marine peptide powder and soybean peptide powder,compare the differences between the four kinds of methods,Kjeldahl method;biuret method;Coomassie Brilliant Blue G250 method and Lowry method. Results: The measured results in the four kinds of methods have significant differences. Conclusion: Lowry method measured results are accurate,reliable,and the method of high sensitivity,easy to operate,the relative other three kinds of method is more suitable for assay of oligopeptides.
