-"This flowers are wonderfully fragrant, perceived by humans as sensual as probably no other flower can offer, something like warm vanilla cream, also tender floral and very skinny. This olfactory and sensual delight is mainly due to the complex interaction of linalool, methyl salicylate, geraniol, (E)-geranylacetone, jasmone, anisaldehyde, (E)-2,3-dihydrofarnesal, (E)-nerolidol, (Z)-dec-7-eno-4-lactone (the so-called γ-jasminolactone), decano-5-lactone, (Z)-dec-7-eno-5-lactone (the so-called jasmine lactone), (E,E)-farnesol, 1H-indole, and benzyl salicylate."
