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