摘要：

Three new neo-clerodane diterpenoids (14,15-dehydroajugareptansin, 3 beta-hydroxyajugavensin B and 3 alpha-hydroxyajugamarin F4), have been isolated from aerial parts of Ajuga reptans cv Catlins Giant, together with the known compound, ajugareptansin. The structures were determined by H-1 and C-13 NMR spectroscopy and MS. Insect antifeedant testing of all four compounds revealed that 14,15-dehydroajugareptansin had significant activity against sixth stadium larvae of Spodoptera littoralis.
