Abstract
In order to find a high-speed countercurrent chromatography solvent system
that can be used as a general prefractionation step for anthraquinone, the
crude extracts of five traditional Chinese medicines, Radix rubiae, Rhizoma
polygoni cuspidati, Semen cassiae, Radix et rhizoma rhei, and Aloe were se
parated with a two-phase system composed of CHCl3:CH3OH:H2O = 4:x:2 in whic
h x was between 3 and 4 for different samples. The fractionated components
were identified on TLC. This solvent system gave a good separation in most
of the anthraquinones.
