Summary: | Fifteen previously undescribed minor iridoid glycosides, including four monomers and eleven dimers, were isolated from the fruits of Cornus officinalis Sieb. et Zucc. Their chemical structures were determined on the basis of spectroscopic data and chemical evidence. All of the isolated compounds were evaluated for their effects of the glucose consumption on the insulin resistant HepG2 cells, and four compounds, named cornuofficinalisides F, H, L, and O, increased the glucose consumption significantly at 10 μM, the EC50 values of them were determined to be 0.898, 1.625, 0.923, and 8.589 μM, respectively. Moreover, the four compounds could improve the ability of glucose uptake significantly in insulin resistant HepG2 cells.
