title: [Study on HPLC fingerprint of Herba Veronicae Dilatatae].
abstract: OBJECTIVE
  To establish HPLC fingerprint of Herba Veronicae Dilatatae.
  
  
  METHODS
  Beckman C18 column was used,with mixtures of 0.5% ice acetic acid-methanol as mobile phase. The flow rate was 1 mL/min. The wavelength of detection was 254 nm.
  
  
  RESULTS
  After the mutual mode of HPLC fingerprint was set up, comparsion of similar degree with the medicinal materials of different batch were carried out.
  
  
  CONCLUSIONS
  According to the selected chromatographic conditions, a good fingerprint has been described. The method is simple, accurate and reproducible. It may have practical value for the quality control of samples of Herba Veronicae Dilatatae.
