title: [Studies on the fingerprint of radix notoginseng and its preparation].
abstract: OBJECTIVE
  A fingerprint of raw material, extracted and injections of radix notoginseng has been studied and provides the quality information.
  
  
  METHODS
  Polaris C18-A column was used, with mixtures of acetonitrile and water as mobile phase in a gradient mode. The wavelength of measurement was 203 nm.
  
  
  RESULTS
  According to the selected chromatographic conditions, a good fingerprint of radix notoginseng and its extract, preparation has been described.
  
  
  CONCLUSIONS
  The method is simple, accurate with good reproducibility. It may be practical value for the quality control of sample for radix notoginseng and its preparation.
