title: [Establishment of a TLC identification method for xuanshen(radix scrophulariae)].
abstract: OBJECTIVE
  To establish a TLC identification method for Xuanshen(Radix Scrophulariae).
  
  
  METHODS
  Using TLC with harpagoside and harpagide as reference substances.
  
  
  RESULTS
  A TLC identification method of Xuanshen has been established. The specificity of the method has been proved by a comparative detection of Xuanshen from different habitats and several crude drugs which are easily confused with Xuanshen.
  
  
  CONCLUSIONS
  The method is simple, accurate and reliable.
