In the presented study, Central European Corydalis species, namely C. cava, C. intermedia, C. pumila, and C. solida were investigated by nonaqueous capillary electrophoresis-electrospray ion trap mass spectrometry (NACE-ESI-MS) utilizing an electrolyte consisting of 50 mM ammonium acetate, 1 M acetic acid and 10% methanol in acetonitrile, applying a separation voltage of 30 and 20 kV for 1 s for injection. Isopropanol-water (1:1) was used as sheath liquid at a flow-rate of 3 microl/min. Peak… CONTINUE READING
