Eleven new steroidal alkaloids, along with nine known related compounds, were isolated from the bulbs of . Seven pairs of diastereomers were identified, including six and four 20-deoxy cevanine-type steroidal alkaloid diastereomers with molecular weights of 413 and 415, respectively. Structures were elucidated based on spectroscopic data analysis, chemical derivatization, and single-crystal X-ray diffraction analysis. Compounds , , , , , and exhibited significant cytotoxic activity against non-small-cell lung cancer with CC values from 6.8 ± 3.9 to 12 ± 5 μM.
