-Main components of the collected 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%). \\+Main constituents of the collected flower scent (223µg/6h) were 1.8-cineole (25.5%), methyl benzoate (18.7%), geraniol (17.9%), and α-terpineol (10.6%).

 "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, one typical for the day and another, for nighttime (Fig. 4). The major components of B. suaveolens flower scent were 1,8-cineol, trans-β-ocimene, β-myrcene, sabinene, citronellal, α-terpineol, benzyl alcohol, and methyl salicylate. Flowers generated less volatiles during the morning and up to 3 p.m., but in the afternoon, after sunset and mostly at night, their release  "At that time, the flower smell used to be particularly rich, deep, and very intensive.
