- | "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%), | + | 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 maximum quantity of volatiles is generated by the flowers of B.suaveolens during nighttime, with a peak at around 9 p.m.:\\ | ||
+ | "At that time, the flower smell used to be particularly rich, deep, and very intensive. As it can be appreciated from Table 3, the flower volatile composition varied from hour to hour. Principal component analysis (PCA), applied to the study of B. suaveolens volatiles, permits the differentiation of two groups of flower scent compositions, | ||
