Purification of di-13C-β-ODAP. NMR analysis of fractions FI to FIII pooled from ion-exchange chromatography. a 1H NMR spectra of fraction FI to FIII (see Fig. 3) compared to a spectrum of an authentic β-L-ODAP standard. The spectrum of Fraction III corresponds to the β-ODAP standard. b 13C-NMR spectrum of FIII in comparison to the spectrum of authentic β-L-ODAP. Two very strong signals at 164.4 and 164.3 ppm correspond to the 13C-labelled oxalyl group
