title: [Study on HPLC fingerprints of Senecio scandens and S. scandens].
abstract: OBJECTIVE
  To develop an HPLC method for fingerprint study of both Senecio scandens and S. scandens.
  
  
  METHODS
  Fingerprints of the two Senecio herbs were compared. And the concentrations of main peaks in them were semi-quantified as chlorogenic acid or hyperoside. Chromatography was performed on a Shiseido Capcell Pak MG II C18 (4.6 mm x 250 mm, 5 microm) column using a gradient elution of acetonitrile-water containing 0.2% acetic acid. And detection wavelength was 360 nm.
  
  
  RESULTS
  Significant difference was found in the fingerprint of the two herbs. Eleven peaks were picked out for the evaluation of S. scandens and S. scandens, respectively. They were identified to be either organic acid compounds or flavones by HPLC-UV and LC-ESI-MS analysis. And semi-quantification of them showed the concentrations of organic acid compounds and flavones in S. scandens were 2.29- and 15.56- folds of those in S. scandens, respectively.
  
  
  CONCLUSIONS
  The developed HPLC method is suitable for the fingerprint study for both of S. scandens and S. scandens. It is robust and producible enough to be used for the quality evaluation on S. scandens.
