Fund Project: The project supported by National Natural Science Foundation of China.

The neuroexcitotoxic nonprotein amino acid β-N-oxalo-L-α, β-diaminopropionic acid (β-N-ODAP) and its isomer α-N-oxalo-L-α, β-diaminopropionic acid (α-N-ODAP) in Panax ginseng C. A. Meyer (cultivated ih Northeastern China), Panax quinquefolius L., Panax notoginseng F.H. Chen (cultivated in Southwestern China), Korean red ginseng and Jilin red ginseng were isolated and identified. Efficient separation and purification methods for β-N-ODAP and α-N-ODAP were developed.
