Electropherograms obtained from the screening assays: a) blank solution (i.e. the substrate solution); b) radix Scutellariae extract at 0.6 mg /mL; c) radix codonopsis extract at 0.6 mg /mL; and d) perphenazine (a known GLDH inhibitor) at 0.125 mM. Assay conditions were as in Fig. 3. Peak identifications: 1) β-NAD+; and 2) β-NADH.
