 [Circadian rhythmicity of fragrance emission in flowers of Hoya carnosa R.Br., Altenburger, R., Matile, P., Planta, 174(2), 1988, 248-252]
-The fragrant volatiles of the typical nightly odor of H.carnosa was collected by dynamic and vacuum headspace analysis. The product of the vacuum process had superior organoleptic properties, containing mainly isoamyl alcohol (isopentanol, 25%) and linalool (23%), furthermore sabinene (0.6%), benzaldehyde (1.5%), benzyl alcohol (14%), 2-phenyl ethanol (4%), methyl salicylate (2.5%), endo-2-hydroxycineole (4%) and eugenol (0.3%). \\
+The fragrant volatiles of the typical nightly odor of H.carnosa was collected by dynamic and vacuum headspace analysis. Although collected from a non-fragrant flower at daytime, the composition of the vacuum headspace concentrate surprisingly was roughly comparable to that of the fragrant flowers at nighttime. \\
+"Obviously, //Hoya carnosa// stores the volatiles produced in the daytime and releases them at night." \\
