Abstract

A new phenyldilactone, maysedilactone B (1), together with twenty known compounds, were isolated from the aerial parts of Lespedeza cuneata. The structural elucidation of the isolated compounds was primarily based on HR-ESI-MS, IR and 1D and 2D NMR analyses. Compounds 1-8 and 15-21 were tested for cytotoxicity against four human tumor cell lines (A549, HCT116, SKOV3, and HepG2) using MTT method in vitro, while no significant activities were observed for the evaluated compounds.
