The determination of amino acids in blood clam antianaemia oral liquid using HPLC-AccQ-Tag method is reported. The oral liquid reacted with 6-aminoquinolyl-N-hydroxysuccini-mdyl carbamate. Then, the corresponding derivatives were analyzed with an HPLC. The chromatographic conditions were AccQ-TagTM C18 column for amino acids analysis (3.9mm×15cm); mobile phase of program elution sodium acetate solution(pH5.02), acetonitrile, Milli-Q water. The amino acids'AQC deriatives were detected at 248nm with a UV-detector. Eighteen kinds of amino acids were completely determined in 35 minutes.
