title: [Preparative separation of alkaloids from Cortex Phellodendri by high speed countercurrent chromatography].
abstract: High speed countercurrent chromatography was successfully applied to the separation of alkaloids from Cortex Phellodendri with a two-phase solvent system composed of CHCl3-CH3OH-0.5 mol/L HCl (2:1:1, volume ratio). Some alkaloid components were obtained, and identification of berberine was made by thin-layer chromatography.
