title: [Comparison of HPLC characteristic fingerprints of stems and leaves of Penthorum chinense].
abstract: OBJECTIVE
  To establish and compare the HPLC characteristic fingerprints of stems and leaves of Penthorum chinense for its scientific evaluation and quality control.
  
  
  METHODS
  The HPLC fingerprints of the stems and leaves were established and analyzed with Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (Version 2004A), and chromatograms of stems and leaves were generated as the representative standard fingerprints. The cluster analyis was carried on by SPSS 16. 0.
  
  
  RESULTS
  The similarity of HPLC characteristic fingerprints from the stems and leaves was only 0.340 - 0.735; Stems from 8 habitats were classified into one group and leaves from 7 habitats (except leaf from Sichuan Wanyu) were classified into another group.
  
  
  CONCLUSIONS
  The HPLC characteristic fingerprints from the stems and leaves are significant different, and the latter can be applied for quality control owing to high similarity; Making a reasonable choice of different parts depends on the pharmacodynamics and clinical demands.
