A new bufadienolide (1), two new bufadienolide glycosides (2and3), a new ecdysteroid (4), and four known compounds (5–8), were isolated from the whole plants ofHelleborus nigerL. (Ranunculaceae). The structures of the new compounds (1–4) were determined by spectroscopic analysis, including 2D NMR spectral data, and hydrolytic studies. Compounds1–6showed cytotoxicity against HL-60 human leukemia cells, A549 human lung adenocarcinoma cells, and SBC-3 human small-cell lung cancer cells, with IC50values ranging from 0.0055 to 1.9 µM. HL-60 cells treated with either3or4showed apoptosis characteristics, such as nuclear chromatin condensation, accumulation of sub-G1cells, and activation of caspase-3/7.
