This article is published with open access at Springerlink.com Abstract: Three new limonoids (1–3) and a new intact triterpenoid (4), along with three known constituents (5–7), were isolated from the dried kernels (after extracting azadirachtin) of Azadirachta indica. The structures of the new compounds 1-benzoyl-3-deacetyl-1-detigloyl salannin (1), 7-tigloyl-12-oxo vilasini (2), azadiralactone (3) and azadirahemiacetal (4) were elucidated by means of spectroscopic analysis. The cytotoxities of these isolated constituents were assayed
