[Studies on the phenylpropanoids from Eucommia ulmoides].Zhongguo Zhong Yao Za Zhi. 2002 Jan; 27(1):38-40.ZZ
To study the chemical constituents from the leaves of Eucommia ulmoides.
The constituents were isolated by chromatography method and the structures were identified on the basis of spectral analysis.
Six compounds, ursolic acid(1), beta-sitosterol(2), p-coumaric(3), caffeic acid ethyl ester(4), chlorogenic acid(5) and syringin(6) were obtained.
Compound 3, 4, 5 were obtained from the plant for the first time.
