 Floral headspace volatiles identified from C.breweri were: linalool (27-38%), trans-linalool oxide (pyranoid, 10-20%), cis-linalool oxide (furanoid, 0.7-1.6%), benzyl acetate (22-42%), benzyl benzoate (3-6%), eugenol (1-5%), methyl salicylate (3-4%), vanillin (0.7-1%), and others. \\

-"... GC-MS analyses of C. breweri floral scent identified (S)-linalool and it’s pyranoid oxide, together with benzyl acetate, as the most abundant volatiles emitted over the course of 4–6 days, with a peak in abundance during the first 36 h (Pichersky et al. 1994). The additional five to 12 floral volatiles identified in our analyses were aromatic esters and alcohols produced by the shikimate pathway...  Six- and 12-h scent collection periods over a time course of 5 days revealed that there were no marked quantitative or qualitative differences in diurnal versus nocturnal emissions, unlike the pronounced circadian rhythmicity of linalool emission in many species of night-blooming plants.
