In the strongly acidic amino acid fraction of the muscle extract of abalone <i>Hariotis discus hannai</i> several acidic ninhydrin positive substances were detected by paper electrophoresis and paper chromatography. They were purified by ion exchange chromatography. One of them, which gave a yellow color with ninhydrin reagent and a blue color with isatin, was obtained as colorless crystals. Its chemical structure was established as L-pyrrolidine-2, 5-dicarboxylic acid (IV) by means of mass, NMR, ORD and IR spectrometries. IV has only been found in a red algs <i>Shizymenia dubyi</i> but not in animal tissues until now.
