 Together with the saturated (R)-delta decalactone, tuberose absolute contained some unsaturated lactones like (S)-jasmine lactone, (R)-tuberolactone and (R)-massoialactone. \\

 "Six unsaturated γ-lactones, (Z)-5-octen-4-olide, (Z)-5-decen-4-olide, (Z)-6-nonen-4-olide, (Z)-6-dodecen-4-olide, (Z,Z)-6,9-dodecadien-4-olide, and tuberolide have been identified for the first time in tuberose absolute (from Polianthes tuberosa L.)." \\
 These components were detected in trace amounts (0.01-0.001%) but may contribute to the rich, heavy floral odor of tuberose absolute with creamy coconut, fatty aldehydic, and tenacious lactonic notes. \\

 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%). \\
