Abstract

The known labdane-type diterpenoids anticopalic acid (1) and 3β-hydroxyanticopalic acid (2) were isolated from extracts of the aerial parts of Vitex hemsleyi Briq. (Labiatae). The acid 1 showed an antifeedant, dose-dependent activity against Spodoptera frugiperda (J. E. Smith) (Lepidoptera:Noctuidae). To our knowledge this is the first report on the antifeedant activity of a labdane-type diterpene against S. frugiperda.
