Eleven new cycloartane-type glycosides, named eremophilosides A-K have been isolated from the aerial parts of Astragalus eremophilus. Their structures were elucidated by MS and NMR experiments and the relative configurational analysis of eremophilosides C and D was carried out on the basis of the recently reported J-based method. Additionally, the cytotoxic activity of these compounds in MCF7 and U937 cell lines was evaluated. All tested compounds, except eremophilosides B, C, and J were found to inhibit slightly the growth (controlling the cell cycle) and/or to induce death processes in U937 cell line, the most susceptible cell line. Eremophilosides A and K resulted the most effective to induce cell death, the first by necrosis while the latter by apoptosis.
