Objective Comparison the methods of amino acid analyzer (AAA) and ultra-performance liq-uid chromatography (UPLC) for determination of hydrolysis amino acids in human milk. Methods Hydroly-sis amino acids were analysed with C18+column and AQC precolumn derivation by UPLC method;and ion ex-change chromatography column and ninhydrinpostcolumn derivation by AAA method. Results Two methods provided similar validation results. The difference of analysis result using two methods was below 4.65%. Conclusion Both methods can be used for the quantitation of hydrolysis amino acids.
