 Major constituents of the vacuum headspace concentrate from the flowers were (E)-ocimene (38%), 1,4-dimethoxybenzene (9.7%), (Z)-3-hexenol (9.5%), lilac aldehydes (7.8%), lilac alcohols (4%), anisaldehyde (2.4%), and indole (1.8%). Minor amounts of unusual ethers were present: 1,2,4-trimethoxybenzene (0.5%), methylbenzylether (0.1%), 1,2-dimethoxybenzene (tr), and 2-methoxymethylanisole (tr). \\ Major constituents of the vacuum headspace concentrate from the flowers were (E)-ocimene (38%), 1,4-dimethoxybenzene (9.7%), (Z)-3-hexenol (9.5%), lilac aldehydes (7.8%), lilac alcohols (4%), anisaldehyde (2.4%), and indole (1.8%).

 +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). \\
