in this paper the capability of this high-speed counter-current chromatography was demonstrated on separation of two sets of samples obtained from medicinal herbs : a synthetic mixture of 3'-hydroxygenkwanin , luteolin and apigenin was separated on a two-phase solvent system composed of chloroform-methanol-water ( 4:3:2 , v/v/v ) and a crude ethanol extract from anisodus tangulicus ( maxin ) pasch on chloroform-0.07 m sodium phosphate ( ph 6.4 ) ( 1:1 , v/v ) .
