title: [Isolation and identification of hetisine-type alkaloids from Aconitum coreanum by high speed countercurrent chromatography].
abstract: OBJECTIVE
  To search for more bioactive compounds from the roots of Aconitum coreanum (Lèvl.) Rapaics.
  
  
  METHODS
  High speed countercurrent chromatography was successfully applied to the separation of alkaloids from Aconitum coreanum. The structures were elucidated by their physicochemical properties and spectroscopic analysis.
  
  
  RESULTS
  Two-phase solvent system composed of CHCl3-CH3OH-0.2 mol x L(-1) HCl (10:3:3, volume ratio) was used in this experiment, eight alkaloids were obtained from the roots of Aconitum coreanum, which were identified as: 2alpha-propionyl-11alpha,13beta-diacetyl-14-hydroxyhetisine (I), Guanfu base P (II), Guanfu base G (III), Guanfu base F (IV), Guanfu base Z (V), Guanfu base O (VI), Guanfu base A (VII), Guanfu base B (VIII).
  
  
  CONCLUSIONS
  Compound I is a new alkaloid, named Guanfu base R.
