title: [HPLC fingerprint of Pericarpium Citri Reticultae from Guangdong province].
abstract: OBJECTIVE
  To establish chromatographic fingerprint of Pericarpium Citri Reticultae from Guangdong province by HPLC and comparison of citrus herbs similarity with different strains and different origin, it was expected to fix standard of quality control.
  
  
  METHODS
  26 samples' analysis was performed on Diamonsil C18 column (250 mm x 4.6 mm, 5 microm) with gradient mobile phase of acetonitrile-1% acetic acid,fingerprint was finished in 65 min, the monitoring wavelength was at 330 nm with the flow rate of 1.0 mL/min.
  
  
  RESULTS
  Establishing the fingerprint of Pericarpium Citri Reticultae from Guangdong province, 17 common peaks were found in the HPLC fingerprints from different sources, the similarity of Pericarpium Citri Reticultae from Guangdong province above 0.975 and quite different for different origin drugs.
  
  
  CONCLUSIONS
  This method is simple, accurate with good reproducibility, and can be used specifically for the quality control of Pericarpium Citri Reticultae from Guangdong province.
