+Main components of the flower scent (223µg/6h) were 1.8-cineole (25.5%), methyl benzoate (18.7%), geraniol (17.9%), and α-terpineol (10.6%). Minor components were benzaldehyde (1.8%), benzyl alcohol (1.4%), sabinene (1.6%), myrcene (6.1%), limonene (3.3%), (Z)-β-ocimene (0.1%), (E)-β-ocimene (0.7%), linalool (1.0%), citronellal (0.5%), neral (0.2%), geranial (1.1%), geranyl acetate (0.1%), citronellol (0.6%), nerol (0.3%), and nerolidol (3.8%). \\

 "The floral essential oils of Brugmansia suaveolens, from Monteverde, Costa Rica, were collected at three different times of the day by hydrodistillation and the oils analyzed by gas chromatography-mass spectrometry (GC-MS). The floral essential oil showed a dramatic change in composition between the freshly opened night (white) blossoms and the rose-colored senescent blossoms the following day. The white blossoms were dominated by 1,8-cineole (72.1%), (E)-nerolidol (11.7%), α-terpineol (5.3%), and phenethyl alcohol (3.2%), notably different from headspace analyses of B. suaveolens reported previously. The floral essential oil from "rose-colored" senescent blossoms of B. suaveolens showed dramatic decreases in 1,8-cineole (2.0%), (E)-nerolidol (1.9%), and phenethyl alcohol (not detected), with concomitant increases in heptanal (10.2%), nonanal (17.4%), terpinen-4-ol (10.5%), and [[http://www.thegoodscentscompany.com/data/rw1041871.html|megastigmatrienones]] (35.5%)." \\
