title: [HPLC fingerprint of Rhizoma Polygoni Cuspidati].
abstract: OBJECTIVE
  To establish the HPLC fingerprint of Rhizoma Polygoni Cuspidati (Polygonum cuspidatum).
  
  
  METHODS
  The HPLC separation was carried with Diamonsil C18 column and eluted with a gradient from methanol and 0.1% phosphoric acid, the detection wavelength was at 230 nm and recording 70 min. The similarity of chromatograms was compared by mean of the software from Zhongnan University.
  
  
  RESULTS
  The constituents of P. cuspidatum were well separated by HPLC, and the similarity was above 0.80.
  
  
  CONCLUSIONS
  The method can be used for the study of fingerprints of Rhizoma Polygoni Cuspidati.
