Abstract :The heartwood of Azadirachta indica (Meliaceae) yielded a new steroid (2a, 3b, 4b-trihydroxypregnan-16-one) and 2 known steroids (2b, 3b, 4b-trihydroxypregnan-16-one and 2a, 3a, 4b-trihydroxypregnan-16-one). Their structures were elucidated through spectral studies including 2D NMR (COSY, NOESY, J-resolved, HMQC, HMBC) experiments.Keywords : Azadirachta indica, Meliaceae, heartwood, steroids, 2a, 3b, 4b-trihydroxypregnan-16-one, 2b, 3b, 4b -trihydroxypregnan-16-one, 2a, 3a, 4b-trihydroxypregnan-16-one.
