 +Major component of the volatiles emitted from living flowers of Rangoon creeper is (E,E)-α-farnesene (besides unknown hydrocarbon, HS-SPME/GC-MS). 2,2,6-Trimethyl-6-vinyl-tetrahydro pyran-3-one (7.8%), quinoline 4-carbonitrile (5.8%), hexyl tiglate (4.5%), (Z)-3-hexenyl benzoate (2.0%) are also important constituens. Esters like methyl-, hexyl- and benzyl benzoate, (Z)-3-hexenyl-2-methyl butyrate, and (E)-2-phenylethyl tiglate give further sweet, fruity, green and earthy (benzyl tiglate 1%) notes. A creamy one is added by δ-decalactone (1.2%). \\
