title: [Research on the quality changes in pre- and post-processed pieces of Eucommia ulmoides].
abstract: OBJECTIVE
  To study the quality changes in pre- and post-processed pieces of Eucommia ulmoides Oliv.
  
  
  METHODS
  The changes of the content of pinoresinol diglucoside, extract and fingerprint were studied.
  
  
  RESULTS
  Pinoresinol diglucoside contents in post-processed pieces were lower than those in pre-processed and alcohol extract had different changes because of its different habitats. Eucommia ulmoides consists of 11 common peaks, the one processed by salt-water consists of 8 Peaks.
  
  
  CONCLUSIONS
  Processing can reduce the content of pinoresinol diglucoside. Alcohol extract has different changes. Eucommia ulmoides common peaks of its fingerprint reduce and mostly components descend after processed by salt-water.
