Abstract

Stäng
- Linden (Tilia cordata) bark contains antifeedants effective against the large pine weevil, Hylobius abietis. Soxhlet extraction of inner and outer bark resulted in an extract which showed antifeedant activity in a micro-feeding assay. The extract was fractionated by chromatography on silica gel using gradient elution with solvents of increasing polarity. The content of the fractions obtained was monitored by thin layer- and gas chromatography. Fractions of similar chemical composition were merged. Two of the 17 fractions showed antifeedant activity in the micro feeding assay. Nonanoic acid was identified in both of these fractions. Subsequent testing in the micro feeding assay showed that nonanoic acid possessed strong antifeedant activity against H. abietis adults.
