ABSTRACT=<p>Elesesterpenes A–K (<bold>1</bold>–<bold>11</bold>), eleven new lupane-type triterpenoids, triterpenoid glycosides, and nortriterpenoid were isolated from the leaves of <italic>Eleutherococcus sessiliflorus</italic>. Their structures and relative configurations were completely elucidated by a combination of diverse methods including physical, spectroscopic data. The absolute configuration of elesesterpenes A–B (<bold>1</bold>–<bold>2</bold>) was defined by single-crystal X-ray diffraction. Meanwhile, all the isolates were evaluated for anti-inflammatory activities on lipopolysaccharide-induced nitric oxide production in BV2 microglial cells, and antiproliferative activities against human hepatoma (HepG2), human lung adenocarcinoma (A549), and human glioma cells (LN229) <italic>in vitro</italic>. It was found that some of them exhibited obvious anti-inflammatory activities and potent antiproliferative activities.</p>
