Abstract
A new secoiridoid glycoside, 7β-O-dimethyl butanedioate morroniside (1) was isolated from the fruits of Cornus officinalis (Cornaceae) along with the known compound, caffeoyltartaric acid dimethyl ester (2) which was isolated from the family Cornaceae for the first time. Their structures were elucidated by physical and spectroscopic data analysis, including 1D and 2D NMR, ESI-MS and CD experiments.
