 (E)-Ocimene and (Z)-ocimene were the most prominent compounds present in the headspace of lilac flowers, other main components were e.g. α-pinene, β-pinene, 1,4-dimethoxybenzene, and linalool. Minor components included camphene, limonene, camphor, β-bourbonene, 4-methylanisole, phenylacetaldehyde, estragole, 4-methyl acetophenone, 2-methoxybenzyl methyl ether, methyl eugenol, 1,2,4-trimethoxybenzene, piperonal, benzyl tiglate, (Z)-hexenyl benzoate, and indole. \\ (E)-Ocimene and (Z)-ocimene were the most prominent compounds present in the headspace of lilac flowers, other main components were e.g. α-pinene, β-pinene, 1,4-dimethoxybenzene, and linalool.

 The major naturally occurring (5′S)-stereoisomers of lilac aldehydes (sweet, fresh, flowery, pleasant; ODT 0.2-0.4ng/L) have a lower odour threshold by 1-2 orders of magnitude in comparison to lilac aldehydes with (5′R)-absolute configuration (fresh, flowery; ODT 4-20ng/L). \\ The major naturally occurring (5′S)-stereoisomers of lilac aldehydes (sweet, fresh, flowery, pleasant; ODT 0.2-0.4ng/L) have a lower odour threshold by 1-2 orders of magnitude in comparison to lilac aldehydes with (5′R)-absolute configuration (fresh, flowery; ODT 4-20ng/L). \\
