摘要：

Two novel neo-clerodane diterpenoids, distinguished by a unique ether linkage spanning C-1 and C-12, have been isolated from the leaves of Cornutia grandifolia. These two highly oxidized diterpenoids are significant repellents of the leafcutter ant Acromyrmex octospinosus in laboratory bioassays. Two simpler neo-clerodanes isolated from the same plant, identified as the parent carboxylic acids to the methyl esters ajugarin-IV and deacetylajugarin-IV, showed no significant activity in this bioassay at comparable concentrations.
