-Diurnal changes of volatiles collected from the headspace of S.floribunda flowers show methyl benzoate and 1-nitro-2-phenylethane are emitted in the night and linalool 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%). Methyl benzoate (30-80%), linalool (up to 15%) and 1-nitro-2-phenylethane (5-40%) as main volatiles present in the headspace of the flowers showed the same rhythm with peak emissions in the night between hour 18-6. \\ +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.

 "Stephanotis floribunda (Asclepediaceae), a plant that grows in Madagascar and is now a common house plant, emits a number of volatiles from its flowers. Its floral scent has been noted to increase in intensity during the night. At this time prominent scent compounds include benzyl alcohol, benzyl acetate, benzyl benzoate, eugenol, α-farnesene, linalool, linalool oxide, methyl benzoate (MBA), methyl salicylate (MSA), β-ocimene, phenylethyl alcohol, and [[http://www.flavornet.org/info/6125-24-2.html|1-nitro-2-phenylethane]]." \\ "Stephanotis floribunda (Asclepediaceae), a plant that grows in Madagascar and is now a common house plant, emits a number of volatiles from its flowers.

-{{: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..." \\
