| Abstract: | The method for the determination of the content of amino acid in Saccharum alhagi from uygur medicine was established by fluorimetry.Amino acid was extracted from Saccharum alhagi by ultrasound with distilled water,and determined by fluorimetry after derived by 0.1% orthophthalaldehyde（OPA）.The linear range was 3.0952—15.5071μmol·L-1（r=0.9990）.The detection limit was 9.70×10-7mol·L-1.The average recoveries of samples were 93.6%—99.7% with RSD in the range of 1.9%—2.5%.The method is simple,rapid and high sensitivity,which can be used for the determination of the contents of amino acids in natural drugs. |
