Three new <i>ent</i> -kaurene diterpenoid glucosides from the flowers of <i>Inula japonica</i> Thunb.
Three new <i>ent</i>-kaurene diterpenoid glucosides-Inunicosides L (<b>1</b>), M (<b>2</b>), and N (<b>3</b>)-along with five known analogs (<b>4</b>-<b>8</b>) were isolated from <i>Inula japonica</i> Thunb. Their structures were characterised using 1D and 2D NMR, HRESIMS, and electronic circular dichroism analysis. All compounds were assessed for anti-inflammatory activity.
