title: [Identification of the habitat of Ligusticum chuangxiong with chromatographic fingerprinting].
abstract: OBJECTIVE
  To establish the chromatographic fingerprinting for identifying the habitat of Ligusticum chuangxiong.
  
  
  METHODS
  HPLC system was applied to obtain the chromatograms of L. chuangxiong samples from different areas, and 15 peaks were measured from the chromatograms. Then some computer-based methods including principle component analysis, clustering analysis, similarity calculation and fisher factor analysis were applied for data analysis.
  
  
  RESULTS
  There was obvious difference among chromatographic fingerprints of L. chuangxiong samples from different areas. The 15 measured peaks could be used as the fingerprint features.
  
  
  CONCLUSIONS
  Chromatographic fingerprinting can be used for identifying the habitat of L. chuangxiong.
