| Abstract
| - Three new triterpenoids, azadironolide [24,25,26,27-tetranorapoeupha-7α-acetoxy-23ξ-hydroxy-21,23-epoxy-1,14,20(22)-trien-3,21-dione] (1), isoazadironolide [24,25,26,27-tetranorapoeupha-7α-acetoxy-21ξ-hydroxy-21,23-epoxy-1,14,20(22)-trien-3,23-dione] (2), and azadiradionolide [24,25,26,27-tetranorapoeupha-7α-acetoxy-21,23-epoxy-1,14,20(22)-trien-3,16,21-trione] (3), were isolated from the fresh fruit coats ofAzadirachta indica. Their structures have been elucidated through spectral analysis.
