A New Acyclic Diterpene Glycoside from Nicotiana attenuata with a Mild Deterrent Effect on Feeding Manduca sexta Larvae

Amir Reza Jassbi, Simin Zamanizadehnajari, Danny Kessler and Ian T. Baldwin


To investigate the role of secondary metabolites in the feeding behavior of Manduca sexta larvae feeding on Nicotiana attenuata, an aqueous acetone extract of the aerial parts of the plant was subjected to feeding-performance bioassay-guided fractionation. We isolated three 20- hydroxygeranyllinalool glycosides from the leaves of N. attenuata, which acted as mild deterrents to the feeding herbivore M. sexta. One of the diterpenoid glycosides, attenoside (3), is a novel natural product. The structures of the compounds were determined using APCI mass spectrometry and 1- and 2D-NMR spectroscopy.
