[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.
