title: [Study on RP-HPLC fingerprints of Panax quinquefolium from Liuba County in Shanxi Province].
abstract: OBJECTIVE
  To establish a fingerprint analysis method for quality control of Panax quinquefolium from Liuba County in Shanxi Province by RP-HPLC.
  
  
  METHODS
  A gradient mobile system was applied in the experiment. The fingerprints of different samples were compared by similarity evaluation software.
  
  
  RESULTS
  The similarities among different samlpes were high. 14 peaks were identified as the characteristic fingerprints of Panax quinquefolium. All samples contained the same characteristic peaks, but the content difference of each peak among the samples resulted in the difference of their chromatograms.
  
  
  CONCLUSIONS
  This method is precise with good repeatability and good baseline separation of all the chromatographic peaks, so it can be effectively used to assess the quality of Panax quinquefolium.
