To establish a MPLC method for the content determination of resveratrol in Polygonum cuspidatum Sieb. Et. Zucc, Analytical column SOURCE 5RPC ST 4.6/150 was used with a mixture of acetonitrile+water (30+70,volume ratio ) as mobile phase ,with a flow rate of 1ml/min and the UV detection wavelength was 306nm, The linear range was 0.6-1.6mg/ml (r=0.9919). The average recovery of prodatin was 103.0%-90.4%(RSD=7.21%). The method is convenient and accurate.
