 [Relationship between sensory quality and volatile compounds of elderflower (Sambucus nigra L.) extracts., Kaack, K., Christensen, L.P., Hughes, M., Eder, R., European Food Research and Technology, 223(1), 2006, 57-70]
-GC-MS and GC-O were used to identify the volatile compounds of the elder flowers and the sensory properties of the compounds. For the evaluation of the sensory properties of blossoms as well as syrups, sensory evaluation was performed using a trained sensory test panel. Linalool, rose oxide, 6-methyl-5-hepten-2-one, 2-methylbutanal, (E)-2-hexenal, (Z)-3-hexenol, (Z)-3-hexenyl acetate, geraniol, α-terpineol, neral, and β-damascenone showed the highest aroma potential. \\
+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. \\

 "The elderflower concrete is obtained by primary solvent extraction of the flowers, and the absolute is produced through alcoholic washing of this concrete." Elderflower absolute owns a sweet, hay, dried fruit- and tobacco-like odor. \\
