title: [Study on the TLC-fingerprint of Xiatianwu].
abstract: OBJECTIVE
  To develop a method that can well evaluate the quality of Xiatianwu.
  
  
  METHODS
  Methods are researched and discussed to construct the TLC-FP (thin-layer chromatography finger-print) of Xiatianwu to evaluate its quality.
  
  
  RESULTS
  The areas of six evident peaks in the thin-layer chromatography of Xiatianwu are compared with the area of dl-tetrahydropalmatine peak companied with them in the same chromatography. The Rr of every peak and its relative area were acquired to evaluate the quality of Xiatianwu and identify it.
  
  
  CONCLUSIONS
  The TLC-fingerprint of Xiatianwu can well evaluate the quality of Xiatianwu.
