Abstract: Response surface methodology (RSM) was used to study the technology of preparation of low molecular mass glycopeptide from panax ginseng by dialysis. The effects of three factors, i.e., the ultrafiltrate concentration before dialysis (A), dialysis time (B) and water consumption (C) on the content of glycopeptide were investigated. The optimal conditions for dialysis were ultrafiltrate concentration 0.6 g/mL, dialysis time 5 h 1 min 48 s and water consumption 3.92 L. The experimental values (79.26 %) agree with the predicted values(78.99 %). The panax ginseng peptide with relatively high purity can be prepared by dialysis. A model equation obtained can be used to predict the experiment through the RSM.

Key words: Panax ginseng, glycopeptide, dialysis, response surface metnod (RSM)
