[Research on the quality changes in pre- and post-processed pieces of Eucommia ulmoides].
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.
