ABSTRACT
Objective To study the fingerprint of Polygonum cuspidatum from various regions by HPLC and provide technical support for the identification.Methods HPLC conditionsthe chromatographic column was Agilent ZORBAX SB-C18 (4.6 mm × 250 mm,5 μm);the mobile phase was 0.1% formic acid in water and acetonitrile (A-B);gradient elution ;the de-tection wavelength was 306 nm ;the flow rate was 1 ml/min;the column temperature was 30 ℃ ;injection volume was 20 μl. Results The HPLC gradient conditions could effectively separate polydatin,resveratrol,emodin and emodin ether,etc.Con-clusion This method is stable,effective and durable,which is instructive to the herbs data identification of Polygonum cuspi-datum.
