Three new phenolic compounds 1, 2, and 3 have been isolated from Eucommia ulmoides by repeated column chromatography. Their structures were identified as (+)-erythro-7-O-ethylguaiacylglycerol (1), (–)-erythro-7-O-ethylguaiacylglycerol (2), and 1,3-propanediol-2-O-4′ -(3′ ,5′ -dimethoxy-1′ -hydroxymethyl)phenyl ether (3).
