title: [HPLC fingerprint of the antiarrhythmic fraction of Valeriana officinalis].
abstract: OBJECTIVE
  To establish HPLC fingerprints of the Antiarrhythmic fraction of Valeriana officinalis.
  
  
  METHODS
  Agilent C18 (250 mm x 4.6 mm, 5 microm) column was used and the acetonitrile-water was chosen as the mobile phase in a gradient mode. The column temperature was 380 degrees C and the detection wavelength was 218 nm. The detection time was 70 min, and the flow rate was 1.0 mL/ min.
  
  
  RESULTS
  Fifteen characteristic peaks were indicated in HPLC fingerprints. The relative retention time and the ranges of relative areas of the common peaks were also determined.
  
  
  CONCLUSIONS
  This method is simple and accurate with a good reproducibility and provides a reference standard for the quality control of Valeriana officinalis.
