A method is described for the simultaneous determination of beta-alanine, beta-aminoisobutyric acid and gamma-aminobutyric acid in biological materials. Amino acids including these beta- and gamma-amino acids were derivatized with 4-dimethylaminoazobenzene-4'-sulfonyl (dabsyl) chloride and dabsyl amino acids formed were separated by
