title: [Study on the infrared fingerprint of Evodia rutaecarpa based on the methods of sequential analysis of dual-indexes].
abstract: OBJECTIVE
  To establish a method to identify the different origins of herba Evodia rutaecarpa by IR and provide a new technique for their identification and quality evaluation.
  
  
  METHODS
  The herba materials were extracted by chloroform and absolute alcohol, the powder and the extracts of Evodia rutaecarpa were mixed and pelleted with KBr. The slides were detected within 4000 - 400 cm(-1) by FIR spectrophotometry. The Difference of samples was studied.
  
  
  RESULTS
  The infrared spectrums of Evodia rutaecarpa extracted by chloroform were obviously different.
  
  
  CONCLUSIONS
  The method can be used to identify and appraise the different origins of herba Evodia rutaecarpa.
