抄録

The ethanolic extracts of short-necked clam, Tapes japonica, were found to contain three acidic amino acids in almost the same fractions of ion exchange chromatography. They were isolated by ion exchange chromatography, followed by partition chromatography using Sephadex G-25. Two compounds were identified as meso-α-iminodipropionic acid (I) and D-α-iminopropioacetic acid (II) on the basis of comparison of Rf values in paper chromatograms and IR spectra with the authentic specimens. This result suggests a wide distribution of both I and II in molluscs. The remainder, which was similar to I and II in its ion exchange column chromatography and paper electrophoretic behaviors, was inferred to be L-threo-β-hydroxyaspartic acid (III) from the results of the elemental analysis and mass, NMR, ORD, and IR spectrometries. Its structure was also confirmed by comparison with the authentic specimen. This is the first report of III isolated from marine organisms.
