Abstract

From the green leaves of Eucommia ulmoides Oliv., 12 compounds were isolated: asperuloside, asperulosidic acid, scandoside 10-O-acetate, deacetyl asperulosidic acid, geniposidic acid, aucubin, isoquercetin, quercetin 3-O-sambubioside, rutin, astragalin, kaempherol 3-O-rutinoside and chlorogenic acid. The structures were determined on the basis of spectral data.
