摘要

The chemical constituents of Viburnum formosanum Hayata subsp. leiogynum Hsu have been studied for the first time. As a result, two new iridoids bearing a dioxatricyclodecane skeleton have been isolated and elucidated by extensive spectroscopic analysis from EtOAc/MeOH (V: V=1 : 1) extract of leaves of the title plant.
