title: [Evaluation of quality coherence of prepared slices of polygoni cuspidati rhizoma commercially available in China based on HPLC fingerprint].
abstract: OBJECTIVE
  To evaluate the quality coherence of the prepared slices of Polygoni Cuspidati Rhizoma commercially available in China and provide a reference for their quality evaluation.
  
  
  METHODS
  The fingerprints were obtained using HPLC method, and analyzed with Chromatographic Fingerprint Similarity Evaluation System (2004A Version) provided by Chinese Pharmacopoeia Commission. The experiment was carried out with an Agilent TC-C18 column (250 mm x 4.6 mm, 5 microm) using acetonitrile-0.05% aqueous solution of phosphoric acid as mobile phase at the flow rate of 1.0 mL/min, detection wavelength of 230 nm, and temperature of 25 degrees C.
  
  
  RESULTS
  The fingerprint for Polygoni Cuspidati Rhizoma was established. 21 common characteristic peaks were identified and the similarities of 24 batches of prepared slices of Polygoni Cuspidati Rhizoma were between 0.882 - 0.988.
  
  
  CONCLUSIONS
  The quality of the prepared slices of Polygoni Cuspidati Rhizoma commercially available in China is comparable.
