"Four Nicotiana species in section Alatae sensu strictu have flowers that emit large amounts of 1,8 cineole, with smaller amounts of monoterpene hydrocarbons and α-terpineol on a nocturnal rhythm. This pattern suggests the activity of a single bio-synthetic enzyme (1,8-cineole synthase) with major and minor products; however, several terpene synthase enzymes could con-tribute to total monoterpene emissions... Flowers of N.alata emitted more than twice as much fragrance as any other species, particularly at night [~1000 ng per g dry mass flower per h], and related species in section Alatae also were strongly scented." \\ | "Four Nicotiana species in section Alatae sensu strictu have flowers that emit large amounts of 1,8 cineole, with smaller amounts of monoterpene hydrocarbons and α-terpineol on a nocturnal rhythm.

Main compounds of the flower scent were 1,8-cineole, linalool, 3-methylbutyloxime, (E)-nerolidol, (E,E)-farnesal, α-terpineol, β-pinene, myrcene, sabinene, and limonene. Minor components were e.g. α-pinene, ocimene, linalool oxides, nerol, geraniol, geranyl acetone, zingiberene, farnesene, farnesol, benzaldehyde, salicylaldehyde, eugenol, isoeugenol, methylsalicylate, amyl benzoate, amyl salicylate, prenyl salicylate, and benzyl salicylate. \\ | Main compounds of the flower scent were 1,8-cineole, linalool, 3-methylbutyloxime, (E)-nerolidol, (E,E)-farnesal, α-terpineol, β-pinene, myrcene, sabinene, limonene, and 1-nitro-3-methylbutane.
