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