 "It is found that the CO2 method of fractionation of pentane extract is a practical process providing an organoleptically superior product, though the later is not still totally free from waxes. The subcritical CO2 extract of flowers contains the desirable odoriferous compounds with lower amounts of waxy substances and is organoleptically superior. The major components detected in the extracts are (E)- and (Z)-linalool oxides (furanoid form), 2,2,6-trimethyl-6-vinyl-3-keto-tetrahydropyran, 2,2,6-trimethyl-6-vinyl-3-hydroxy-tetrahydropyran (linalool oxide pyranoid form), (E,E)-α-farnesene, (Z)-3-hexenyl benzoate and benzyl benzoate and a tentatively identified compound quinoline carbonitrile along with some waxy components." \\ "It is found that the CO2 method of fractionation of pentane extract is a practical process providing an organoleptically superior product, though the later is not still totally free from waxes.

 +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 whiff is added by δ-decalactone (1.2%). \\
