title: Antifeedant activity of metabolites from Viguiera tucumanensis.
abstract: Several terpenoids and clerod-14-ene-3alpha, 4beta,13xi-triol (1), the main compound of V. tucumanensis, were isolated and bioassayed. The clerodane 1 showed higher antifeedant activity than other related compounds. Structure-activity relationships are also discussed.
