title: [Study on applying principle component analysis to data processing on chromatographic fingerprints for Pinellia Cum Bile].
abstract: OBJECTIVE
  To explore the utility of principle component analysis (PCA) on chromatographic data for quality control to Dannanxing (Pinellia Cum Bile).
  
  
  METHODS
  Chromatographic fingerprints of sample were determined by TLC, PCA and multivariat analysis were used for data processing.
  
  
  RESULTS
  The quantitative differences among samples procesed with different biles and heating time were found with the method.
  
  
  CONCLUSIONS
  PCA could be used in data processing for chromato-gramphic fingerprints of Dannanxing.
