Abstract A new cytotoxic salannin-class limonoid alkaloid, azadiramide A (1), was isolated from seeds of Azadirachta indica A. Juss. Its structure was elucidated by extensive analysis of spectroscopic data and quantum chemical calculation. Compound 1 is a rare salannin-class limonoid alkaloid. To our best knowledge, only two compounds belonging to this type were so far found. It showed inhibitory activity against human breast cancer MDA-MB-231 cell line with IC50 value of 2.70 ± 0.63 μmol/L.
