"... Nymphaea caerulea with all those common names that captivated the hearts of the Egyptians, both with its appearance and with its intensely sweet aromatic-floral, yet refreshing, rather hyacinth-like perfume and its association with the sun god Ra...not even a specialist can imagine the synesthetic experience offered by these wonderful blue flowers."\\
Not a special compound, but a special delicate equilibrium of ten or so compounds makes this scent by the interaction of benzyl acetate (26.0%), anisaldehyde (0.1%), anisyl alcohol (0.2%), (E)-cinnamyl acetate (1.7%), and cinnamyl alcohol (1.3%), together with a series of derivatives of (E,E)-undeca-3,5-dien-2-one (0.2%), (E)-undec-5-en-2-one (1.7%), (E)-undec-5-en-2-ol (0.2%), (E)-undec-5-en-2-yl acetate (0.3%), and a distinct aura is added by α-ionone and β-ionone. \\
