A rapid and simple method is presented for determining neuro-excitatory nonprotein amino acid 3-N-oxalyl-2,3-diaminopropionic acid (beta-ODAP) and non-protein amino acids in Lathyrus sativus. Seed and foliage extracts of Lathyrus sativus were treated with 1-fluoro-2,4-dinitrobenzene (FDNB) and a reversed-phase high-performance liquid
