title: [Constituents of essential oil from different processing drynesses of Radix Angelicae Dahuricae].
abstract: OBJECTIVE
  To analyze the constituents of essential oil from different processing drynesses of Radix Angelicae Dahuricae.
  
  
  METHODS
  Water steam distillation and GC-MS were used. Relative contents were determined by area.
  
  
  RESULTS
  37 compounds were identified. The constituents of essential oil the constituents from Radix Angelicae Dahuricae by insolation, drying and microwave dryness were similar, but one by dryness after sulfurizing and dryness after perspiring were different.
  
  
  CONCLUSIONS
  Dryness after sulfurizing and dryness after perspiring are not fit for the dryness of Radix Angelicae Dahuricae.
