-"The volatiles of European bird cherry flowers were enriched by the vacuum headspace methodIn the obtained odor concentrate more than 70 compounds were identified by GC/MS. The compounds, which are responsible for the typical odor, are benzaldehyde, 2-phenylethyl alcohol, phenylacetaldehyde, phenylacetonitrile, linalool and a number of nitrogen-containing constituents like indole, methyl anthranilate, anthranilic aldehyde, 2-aminoacetophenone and nicotinic aldehyde." \\+The odor of the flowers "... can be described as clear cherry-flower-like with spects of orange flower, jasmin and elder flower and a characteristic undertone of anthranilate-like compounds." Main constituents of the vacuum headspace concentrate were benzaldehyde, anthranilic aldehyde, benzyl alcohol, 2-phenylethanol, linalool, (E)-8-oxolinalool, and (E,E)-α-farnesene 1,4-Dihydro-2-methyl-2H-3,1-bezoxazine (odor: quinoline-like) as the cyclic product of anthranilic alcohol and acetaldehyde is found in the vacuum headspace concentrate in amounts of 0.1-1%. In pure form it cleaves acetaldehyde in perceptible amounts. \\
