[Studies on chemical constituents from Eucommia ulmoides Oliv].
OBJECTIVE
To study the chemical constituents from Eucommia ulmoides Oliv.


METHODS
The chemical constituents were isolated and repeatedly purified on silica gel column. They were identified and structurally elucidated by means of physio-chemical constants and spectral analysis.


RESULTS
Seven compounds were obtained. They were (-)epicatechin (I), catechin (II), n-octacosanoic acid (III), tetracosanoic-2, 3-dihydroxypropylester (IV), rutin (V), chlorogenic acid (VI), and caffeic acid (VII), respectively.


CONCLUSIONS
Four compounds (II, III, IV, V) were isolated from bark of Eucommia ulmoides Oliv for the first time.
