Diurnal changes of volatiles collected from the headspace of S.floribunda flowers show methyl benzoate (30-80% of total volatiles) and 1-nitro-2-phenylethane (5-45%) are emitted in the night and linalool (up to 15%) mainly during the day. The highly sensitive 2,6-dimethyl-3(E),5(Z),7-octatriene-2-ol and its 5(E) isomer (natural ratio 1:10, sweet floral odor) are present in the headspace of the flowers (evening 2-4%, day 0.1-0.3%). \\ | Diurnal changes of volatiles collected from the headspace of S.floribunda flowers show methyl benzoate (30-80% of total volatiles) and 1-nitro-2-phenylethane (5-45%) are emitted in the night and linalool (up to 15%) mainly during the day.

The flowery-spicy, cinnamon-like smelling 2-nitroethylbenzene (1-nitro-2-phenylethane) was found in the headspace trappings of Stephanotis floribunda at 27%. \\ | The flowery-spicy, cinnamon-like smelling 2-nitroethylbenzene (1-nitro-2-phenylethane) was found in the headspace trappings of Stephanotis floribunda at 27%: "Although it is also somewhat fragrant during the daytime, this most spectacular representative of the Asclepiadaceae starts to emit around twilight a powerful spicy white-floral fragrance based on methyl benzoate, methyl salicylate, isoeugenol, and enormus amounts of 2-nitroethylbenzene." \\ |

{{:stephanotis_floribunda.jpg?500}} \\ | "Methyl benzoate was the dominant component in St. floribunda, accompanied by (E)-ocimene, and benzyalcohol, however, linalool and 1-nitro-2-phenyl ethane were missing from our samples, which were collected in the late afternoon. Both compounds, methyl benzoate and linalool, are commonly reported in the floral odours of moth-adapted plant species... The attractiveness of methyl benzoate and linalool for noctuid moths has been demonstrated in upwind flight experiments in wind-tunnel systems..." \\ |
