摘要

The determination of three aconitine alkaloids (hypaconitine, aconitine, mesaconitine) in five traditional Chinese medicines including two Tibetan medicines, Chuanwu, Caowu, Fuzi, Aconitum Tanguticum Maxim and Aconitum Gymnandrum Maxim by non-aqueous capillary electrophoresis using a new recording mode is described. The dissociation constants of aconitine, mesaconitine and hypaconitine have also been determined by CZE and were 7.71, 6.60 and 6.25, respectively. The separation was achieved by optimizing the applied voltage, the pH and the concentration of the buffer. The electrophoretic medium was 20 mM borax-70% (v/v) methanol (pH 8.5) and an uncoated capillary (50 cm x 75 microm i.d.) was used. Detection was carried out with a UV monitor at 214 nm. The total time for separation and determination was under 13 min.
