title: [Study on the fingerprints of the alkaloids in Sophora flavescens].
abstract: OBJECTIVE
  To establish a method for HPLC fingerprint determination of the alkaloids in S. flavescens.
  
  
  METHODS
  RP-HPLC, linear gradient elution, LC/MS, etc. were used to determine the fingerprint and identify the main peaks in the HPLC fingerprint.
  
  
  RESULTS
  A satisfactory method for HPLC fingerprint determination of the alkaloids in S. flavescens. was established, and 5 peaks in the HPLC fingerprint were identified.
  
  
  CONCLUSIONS
  The perfect fingerprint can be obtained and the method can be used for quality control of S. flavescens.
