| Abstract: | Summary A rapid, simple method for packing capillary electrochromatography (CEC) columns with HPLC stationary phases is described. The basis of the method is the use of a vacuum to suck a slurry of stationary phase into the fused-silica tubing, a procedure which takes approximately ten seconds only, then compression of the stationary phase by means of an HPLC pump. These packed CEC columns have been investigated for the separation of five anthraquinones from rhubarb. Separation of the anthraquinones inRheum palmatum L. under optimized conditions is presented. |
