title: [Quantititive study for chromatographic fingerprints of processed products of Paeonia lactiflora].
abstract: OBJECTIVE
  To explore the utility of Principal Factor Analysis (PFA) in chromatographic data for quality control.
  
  
  METHODS
  Chromatographic fingerprints of processed root pieces of Paeonia lactiflora were determined by HPLC, the PFA was used for data processing.
  
  
  RESULTS
  The quantitative differences among different growing areas and different processing batches were found with the method.
  
  
  CONCLUSIONS
  The method could be used in quality control for monitoring between-batch products of traditional Chinese pharmaceutical process.
