 "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.
