[Identification of the habitat of Ligusticum chuangxiong with chromatographic fingerprinting].

Objective: To establish the chromatographic fingerprinting for identifying the habitat of Ligusticum chuangxiong.

Method: 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.

Result: 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.

Conclusion: Chromatographic fingerprinting can be used for identifying the habitat of L. chuangxiong.
