 The concrete of the flowers contained benzyl cyanide (phenylacetonitrile; 38%) and isoeugenol. \\

-"Among the major constituents were those which were already known such as benzyl cyanide and isoeugenol which represent 4.75% and 0.45% respectively in the absolute, as determined by capillary GC by the internal standard method (int.standard: n-dodecan). Benzyl cyanide was thus the major volatile constituent of the absolute." \\
-Among the >230 other components were e.g. estragole, anethole, benzyl alcohol, phenylethanol, linalool, α-terpineol, lilac alcohols (3 isomers), acetophenone, several aliphatic aldehydes (hexanal, octanal, nonanal) and aromatic aldehydes (benzaldehyde, phenylacetaldehyde, lilac aldehydes, anisaldehyde, vanillin, cinnamal), Z-jasmone, α-ionone, β-ionone, several phenolic compounds like eugenol and ioseugenol, and many esters including cyclic ones like γ-nonalactone and δ-decalactone. 2-Phenylnitroethane was present at 2.55% (GC) or 1.1% (int.standard method) in the absolute. \\
