The separation of Akebia Trifoliata peel oleanolic acid with seven commercial macroreticular resins were studied.The results showed that XDA-1 is optimal resin for the separation of Akebia Trifoliata peel oleanolic acid.On the basis of single factor experiments,influences of solid-liquid ratio,adsorption temperature and adsorption time on the oleanolic acid extraction yield were investigated by response surface optimization.The experimental results showed that extraction yield of oleanolic acid is 0.265 6% in solid-liquid ratio for 1∶8 (g/mL),40 ℃ temperature adsorption 315 min.Predictive value of model on oeanolic acid extraction yield was 0.243 2%.Those results conform with the model prediction.

Key words: Akebia Trifoliata, macroporous resin, oleanolic acid, separation
