-The fragrant volatiles of Phlox paniculata hybrids were collected by dynamic and vacuum headspace analysis. The products of the vacuum process contained mainly 2-pheyl ethanol (12-17%) and linalool (3-9%). Cinnamic alcohol was found only in the vaccum product, together with 3-hydroxy-1-phenyl-2-butanone (1-4%), 3-hydroxy-4-phenyl-2-butanone (3-7%) and 1-phenyl-2,3-butanediol (0.3-6%). Phenylacetaldehyde (1-2%), benzaldehyde (0.3-5%) and benzyl alcohol (0.2-2%) were found in the dynamic headspace and in the vaccum headspace products. lilac alcohols, eugenol methyl ether, isoeugenol methyl ether and germacrene-D are additional main volatiles of Phlox flowers. \\
+Main compounds of a dynamic headspace concentrate from violet Phlox flowers were phenylacetaldehyde (20%), benzaldehyde (5%), lilac alcohols (3%), linalool (2%), and 2-phenylethanol (0.4%). \\

+The flower scent collected using the dynamic headspace adsorption method and analysed by GC-MS showed benzaldehyde (1.5%), phenylacetaldehyde (17.3%), 2-phenylethanol (10.2%), eugenol (1.5%), (Z)-β-ocimene (1.6%), (E)-β-ocimene (40.8%), linalool (3.8%), lilac alcohol A (1.2%), β-cubebene (1.6%), germacrene D (5.5%), 3-methylbutylnitrile (1.0%), 3-methyl syn-butyl aldoxime (2.0%), and 3-methyl anti-butyl aldoxime (1.1%) as main components. Minor components were e.g. methyl benzoate (0.1%), methyl salicylate (0.3%), benzyl alcohol (0.2%), myrcene (0.9%), the lilac aldehydes A/B/C/D (0.4/0.3/0.2/0.1%), lavandulol (0.1%), and the lilac alcohols B/C/D (0.1/0.2/0.6%). \\

 Scent emission analysis of P.paniculata flowers showed the benzenoids, benzaldehyde (14-91 ng/hr/flower), 2-phenylacetaldehyde (14-61 ng/hr/flower) and methyl eugenol (11-47 ng/hr/flower) as main constituents, together with (E)-β-ocimene (13-28 ng/hr/flower). Other components were linalool, lilac aldehyde A, lilac aldehyde B, 2-phenyl acetonitrile, eugenol and methyl isoeugenol as well as nonanal and decanal. \\
