N2 - The volatile profiles from flowers of Nicotiana sylvestris and N. suaveolens were investigated by means of dynamic headspace sampling and capillary gas chromatography. Under conditions of light/dark entrainment both species emitted phenylpropanoid‐derived volatiles (e.g. benzyl alcohol, methyl benzoate) with maximum emission occurring during the dark period. Emission of these compounds was demonstrated to be circadian by continuance of rhythmicity under conditions of constant light and subsequent re‐entrainment to a new light/dark cycle. In contrast, emission of the sesquiterpene hydrocarbon, caryophyllene, from N. sylvestris followed no apparent pattern. The emission of monoterpene hydrocarbons from flowers of N. suaveolens showed diurnal differences only under conditions of light/dark entrainment.
