The parameters of absorption and purification of total anthraquinones in Radix Et Rhizoma Rhei by D301 macroporous resin were investigated in this paper. HPLC was used to analyze the content of total anthraquinones in Radix Et Rhizoma with emodin as control. The appropriate adsorption conditions were: concentration of extract 0.5 g x mL(-1); pH 9; flow rate 1 BV x h(-1). When the 75% ethanol was used as elution and the concentration of HCl was 0.1 mol x L(-1), and the flow rate was 1.0 BV x h(-1), the effect of desorption was satisfactory. D301 resin provided a good effect on the exchang and absorption of total anthraquinones in Radix Et Rhizoma.
