Objective:To determine the content of the 17 types of amino acids in the swine heart tissue. Methods17 types of amino acids in the cardiac tissue of swine were detected by the amino acid analyzer with ninhydrin post-column derivatization. Results:The correlation coefficient (r) of linear equation of these 17 types of amino acid were all above 0.9990 within the range of concentration. The average recoveries of glycine, tyrosine, phenylalanine and arginine were 99.0%, 99.6%, 101.7% and 97.9%(n=6), respectively, and RSD were all less than 2%. Conclusion:The method was simple and reliable that can be used to determine the content of amino acid in the swine heart tissue.
