Abstract: Perchloric acid extracts of tissues of marine invertebrates were analyzed by HPLC on a Waters amino-acid column (25 cm x 4.6 mm) packed with strong cation exchanger. The mobile phase was 0.1 M citrate buffer (pH 3.0) at 0.4 mL min-1 and detection was by post-column derivatization with NaClO (at 60°C) and phthalaldehyde in the presence of 2-mercaptoethanol, with subsequent fluorimetry at 418 nm (excitation at 340 nm). Retention times of alanopine (2,2'-iminodipropionic acid) and strombine (2-methyliminodiacetic acid) were 4.7 and 5.4 min, respectively. Response was rectilinear from 0.05 to 0.25 nmol.
