title: [Studies on fingerprint spectrum of Radix Sophorae Tonkinensis from Guangxi].
abstract: OBJECTIVE
  To set up the fingerprint spectrum of Radix Sophorae Tonkinensis from Guangxi province.
  
  
  METHODS
  HPLC with UV detector was used to analyze matrine and oxymatrine the patterns of Radix Sophorae Tonkinensis from Guangxi province.
  
  
  RESULTS
  The fingerprint spectrum of Radix Sophorae Tonkinensis from Guangxi province was set up. Furthermore, the fingerprint spectrum showed an excellent correlation, and all the parameters of the main co-peaks met the requirements for State Drug Administration's technical regulations on the herb.
  
  
  CONCLUSIONS
  The studies are useful for the standard planting and the quality control of Radix Sophorae Tonkinensis from Guangxi province.
