[Studies on the phenylpropanoids from Eucommia ulmoides].
OBJECTIVE
To study the chemical constituents from the leaves of Eucommia ulmoides.


METHODS
The constituents were isolated by chromatography method and the structures were identified on the basis of spectral analysis.


RESULTS
Six compounds, ursolic acid(1), beta-sitosterol(2), p-coumaric(3), caffeic acid ethyl ester(4), chlorogenic acid(5) and syringin(6) were obtained.


CONCLUSIONS
Compound 3, 4, 5 were obtained from the plant for the first time.
