Leaf surface sesquiterpene alcohols of the potato (Solanum tuberosum) and their influence on Colorado beetle (Leptinotarsa decemlineata Say) feeding

Szafranek, B.; Chrapkowska, K.; Waligora, D.; Palavinskas, R.; Banach, A.; Szafranek, J.

The structures of two previously unknown sesquiterpene alcohols of the potato (Solanum tuberosum) were assigned. The potato alcohols were obtained by steam-distillation, preparative column chromatography, and separation into fractions by HPLC on a silica gel column. The fractions were studied by GC-FID, GC-MS, and NMR spectroscopy. The potato sesquiterpene alcohols were identified as kunzeaol (6-alpha-hydroxygermacra-1(10), 4-diene) and ledol. These two compounds were used in feeding tests with larvae and beetles of the Colorado potato beetle (Leptinotarsa decemlineata Say). In a bioassay, kunzeaol was found to act as a feeding attractant for the beetles
