Abstract

Three unsaturated fatty acid isobutylamides, N-isobutyl-2E,4E,10E,12Z-tetradecatetraen-8-ynamide (1, new), N-isobutyl-2E,4E,12Z-tetradecatrien-8,10-diynamide (2), and N-isobutyl-2E,4E,12E-tetradecatrien-8,10-diynamide (3), were isolated from the leaves and flowers of Chrysanthemum morifolium. The structure of 1 was determined by spectral data interpretation. The concentration of 1 in chrysanthemum varieties was previously positively correlated with host-plant resistance against the western flower thrips, Frankliniella occidentalis.
