  • Determination of Aconitum alkaloids in processed Buza (Cho-0, Salted Buza, Moist-heating Buza, Limed Buza), which had been prepared from the raw tubers of Aconitum chiisanenseb(Ranunculaceae), was established using visible spectrophotometry and high-performance liquid chromatography (HPLC) method especially for Aconitine analysis. Aconitum alkloids were reacted with tetra- thiocy-anatocobalt[II] complex ion to form a stable ion pair. The reaction product was insoluble in water but freely soluble in several organic solvents. 1.2-Dichloroethane was the best extracting solvent among the examined solvents. Spectrophotometry of Aconitum alkaloids at nax. 625 was carried out. The HPLC method for aconitine was carried out using Radial PAK-CN column with gradient solvent system by solvent mixture of acetonitrile and phosphate buffer (pH 3.0) at 4$0^{\circ}C$ and 254 nm. Linear relationship was found between absorbance response and concentration of aconitine in range of 0.45 mM~0.9 mM ($r^2$=0.9949) by spectrophotometry and 0.3 mM~1.2mM($r^2$=0.9983) by HPLC method. These methods have been found to be suitable and reproducible for routine analysis of Aconitum alkaloids and its pharmaceutical preparations.

  • HCl 산성에서 aconitine류 알칼로이드는 Reineke 시액으로 백색의 침전을, 그리고 TCR 시액으로 청색의 침전을 형성하였다. 백색의 침전은 $NH_4OH$ 알칼리성의 물에 녹아 aconitine류 알칼로이드를 유리시키며, 유리된 aconitine류 알칼로이드는 DCE층으로 쉽게 전용되었다. 전용된 DCE층을 분취하여 UV흡광파장을 측정하고 TLC로 분리하였다. 청색의 침전은 DCE층에 전용되므로 전용된 DCE층을 분취하여 UV/Vis.흡광파장을 측정하였다. 이상의 방법으로 aconitine류 알칼로이드를 검출하여 생약이나 제제에서 aconitine류 알칼로이드를 함유한 부자류 생약을 확인할 수 있었다.
