Abstract
A method for detecting amino acid derivatives in which 2-anilino-5-thiazolinone derivatives of amino acids are reacted with an amino compound of fluorescein or rhodamine derivative amino compounds to form phenylthiocarbamyl amino acids derivatives. The phenylithiocarbamyl amino acids derivatives are detected with a high level of sensitivity by a fluorescence spectrophotometer.
