A new tetranotriterpenoid of the limonoid type, 7-deacetyl-17β-hydroxyazadiradione, and the known compound azadiradione, were isolated from the seeds of Azadirachta indica.The structure of the new compound was established by spectroscopic methods.The activity of the new compound as an insect growth inhibitor against Heliothis virescens was found to be greater than of azadiradione and 7-deacetylazadiradione.Key Word Index - Azadirachta indica; limonoids; tetranotriterpenoids; 7-deacetyl-17β-hydroxyazadiradione; azadiradione; 7-deacetylazadiradione; Heliothis virescens; insect growth inhibitor.
