title: A new triterpenoid from Azadirachta indica.
abstract: A new triterpenoid, 1 alpha,7 alpha-diacetoxyapotirucall-14-en e-3 alpha, 21,22,24,25-pentaol (1), and the two known compounds odoratone (2) and 2 beta,3 beta,4 beta-trihydroxypregnan-16-o ne (3) were isolated from a methanolic extract of the seed kernels of Azadirachta indica. Their structures were elucidated on the basis of spectral methods.
