title: [Studies on fingerprint spectrum of Ephedra sinica from Gansu province].
abstract: OBJECTIVE
  To set up the fingerprint spectrum of Ephedra sinica from Gansu province and its extract for controlling the quality.
  
  
  METHODS
  HPLC with UV detector was used to analyze the patterns of Ephedra sinica from Gansu province.
  
  
  RESULTS
  The fingerprint spectrum of Ephedra sinica from Gansu 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 quality control of Ephedra sinica from Gansu province.
