    Abstract:
    OBJECTIVE: To establish a HPLC method for simultaneous determination of resveratrol, emodin, chrysophanol, physcion in root of Polygonum cuspidatum and its extract. METHOD: The separation was performed in a Hypersil ODS C18 column with a mobile phase of Acetonitrile-1%HAc. The flow rate was 1.0 mL x min(-1) and detection wavelength was at 287 nm. RESULT: The mean recovery and RSD of resveratrol, emodin, chrysophanol, physcion was 101.8%, RSD 1.7%; 96.2%, RSD 1.4%; 99.7%, RSD 1.0%; 98.60%, RSD 0.97% respectively. CONCLUSION: The method is accurate, simple and reliable. It can be used for quality control of P. cuspidatum and its extract.
