摘要：

The characterization of five new terpenoids, tirucalla-7,24-dien-16 -beta-o1 (limocinol), tirucalla-8,24-dien-16-one (limocinone), 24,25,26,27-tetranorapotirucalla-7-alpha-acetoxy-21, 23-epoxy-21-alpha-methoxy-1,14-dien-3-one (limocin A), 24,25,26,27-tetranorapotirucalla-7-alpha-acetoxy-21,23-epoxy-23-xi methoxy-1,14-dien-3-one (limocin B) and 24,25,26,27-tetranorapotirucalla (24,25,26,27-tetranorapoeupha)-7-alpha-benzoyloxy-21, 23-epoxy-20-xi-hydroxy-23-xi-methoxy-1,14-dien-3-one (limocinin) from fresh, uncrushed, ripe fruit coatings of Azadirachta indica is described. Their structures were elucidated by spectral studies and chemical reactions.
