 There were major differences between the volatiles (headspace, Tenax) emitted from living tuberose flowers during the day and at night: Limonene (day 8% /night 14%), methyl salicylate (12%/6%), α-terpineol (11%/3.5%), methyl anthranilate (1%/3%), jasmin lactone (0.2%/1%), δ-dodecalactone (0.1%/0.6%). \\ There were major differences between the volatiles (headspace, Tenax) emitted from living tuberose flowers during the day and at night: Limonene (day 8% /night 14%), methyl salicylate (12%/6%), α-terpineol (11%/3.5%), methyl anthranilate (1%/3%), jasmin lactone (0.2%/1%), δ-dodecalactone (0.1%/0.6%). \\

 Nitrogen compounds like N-formyl methyl anthranilate, N-methyl methyl anthranilate, indole (0.02-2%), methyl nicotinate, ethyl nicotinate (warm tobaco-like) and traces of skatol (flowery) certainly bring important contributions to the sweet heavy floral scent of tuberose absolute. \\ [Nicolas Baldovini, Jean-Jacques Filippi, „Natural Fragrant Raw Materials“ in: Buettner, Andrea, ed.
