Capillary zone electrophoresis(CZE) has been performed for determination of resveratrol in Rhizoma Polygoni Cuspidati in a non aqueous solution of tris(hydroxymethyl) aminomethane(THAM) and boric acid with methanol as solvent. The effects of solvent, electrolyte, pH, concentration, running time and voltage were examined. The total separation and determination could be completed within 11 min. Under the optimum conditions, the linear range of trans-resveratrol was 27~540 mg/L. The RSD(n=6) of peak area for resveratrol was 2.46% and the recovery was 103.4%.
