• The natural ^<15>N abundances (δ^<15>N values) were measured for nitrate and free and bound amino acids from the leaves of field-grown spinach (Spinacia oleracea L.) and komatsuna (Brassica campestris L.), as well as ureides and free and bound amino acids in the leaves and roots of hydroponically grown soybean (Glycine max L.) totally depending on dinitrogen. Nitrate from the spinach and komatsuna leaves and ureides from leaves and roots of soybean showed higher δ^<15>N values than the total tissue N and N in free or bound amino acid fractions. The δ^<15>N values of individual free and bound amino acids, determined by GC/C/MS using their acetylpropyl derivatives, were similar in leaf tissues except for proline but varied in soybean root tissues. The order of ^<15>N enrichment was similar in the four samples: aspartic acid>glutamic acid>threonine, proline, valine>glycine+alanine+serine, γ-amino butyric acid, and phenylalanine.
