Abstract

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