 Of 59 volatile compounds found in acidified elderflower syrup extract, 28 were included in four principal components (PC1-PC4). Factor analysis showed that "...important contributors to the floral and elderflower flavour of the extracts were rose oxides, hotrienol, linalool, linalool derivatives and α-terpineol, whereas the fruitiness and freshness of the extracts were mainly due to non-oxidized monoterpenes, aliphatic aldehydes and alcohols." \\ Of 59 volatile compounds found in acidified elderflower syrup extract, 28 were included in four principal components (PC1-PC4).

 +Main volatiles (>1%) of elderflower scent trapped on Porapak SQ were (E)-β-ocimene (68.5%), linalool (10.8%), (Z)-3-hexenol (5.2%), (Z)-β-ocimene (1.3%), and hexenyl acetate (1.1%). Among the minor components were e.g. fruit esters, C6 alcohols, trans-rose oxide (0.01%), cis-rose oxide (0.01%), citronellal  (0.02%), isoleucine methyl ester (0.9%), benzaldehyde (0.02%), hotrienol (0.03%), neral (0.02%), nerol (0.7%), geraniol (0.9%), β-ionone (0.02%), anisaldehyde (0.05%), and indole (0.01%).\\
 +"If we take a  look at the scent composition of the true flowers of Sambucus nigra... we can recognize this Gewürztraminer accord [of cis-rose oxide, nerol oxide, linalool and β-damascenone] in a nearly idealized manner..." \\

 Headspace Solid-Phase Microextraction(HS-SPME) of elderflowers from two austrian main varieties (Haschberg, Rubin) and wild species of Sambucus nigra yielding over 100 substances which are contributing to the typical scent. Most noticeable concentration differences between the two cultivated varieties shown the terpenes ocimene (main component), linalool, linalooloxide and epoxylinalool. Wild species show nearly identic aromatic profiles. \\ Headspace Solid-Phase Microextraction(HS-SPME) of elderflowers from two austrian main varieties (Haschberg, Rubin) and wild species of Sambucus nigra yielding over 100 substances which are contributing to the typical scent.
