title: [Study on HPLC fingerprint of processed Radix Angelicae Dahuricae].
abstract: OBJECTIVE
  To establish HPLC fingerprint analysis for the quality control of processed Radix Angelicae Dahuricae.
  
  
  METHODS
  HPLC fingerprint analysis of processed Radix Angelicae Dahuricae was developed Agilent C18 column (250 mm x 4.6 mm, 5 microm) was used, with mixture of acetonitrile and 5% phosphorous acid mobile phase in a gradient mode. The flow rate was 1.0 mL/min. The wavelength of measurement was 254 nm. Fifteen batches of processed Radix Angelicae Dahuricae were determined.
  
  
  RESULTS
  The methodological evaluation showed that the method had a good repeatability.
  
  
  CONCLUSIONS
  The method can be used to identify and evaluate the quality of Radix Angelicae Dahuricae conveniently.
