Abstract:
Four new limonoids, 1-tigloyl-3,20-diacetyl-11-methoxymeliacarpinin, 3-tigloyl-1,20-diacetyl-11-methoxymeliacarpinin, 1-cinnamoyl-3-hydroxy-11-methoxymeliacarpinin, and 1-deoxy-3-methacrylyl-11-methoxymeliacarpinin, together with a known limonoid, 1-cinnamoyl-3-acetyl-11-methoxymeliacarpinin, were isolated from the extract of the root bark of Melia azedarach. The structures were elucidated by spectroscopy.
