 Although heliotropin (or piperonal) resembles the scent of the flowers (as the name says), there is no trace of this compound present in the headspace. Main volatile compounds emitted by the flowers are benzyl alcohol (21.5%), (Z)-3-hexen-1-ol (17.8%), hexanal (14.8%), p-anisaldehyde (11.0%), 2-phenylethanol (7.3%), benzaldehyde (5.3%), (E)-2-hexenal (4.3%), 1-hexanol (4.3%), 3-phenylpropanol (3.3%), and anis alcohol (1.1%). There are more than 50 compounds found in concentration below 1%, such as e.g. 2-methyl butanal, 3-methyl butanal, methional, (E,E)-2,4-hexadienal, anisole, 4-ethyl 2-butenolide, methyl salicylate, decanal, (E)-cinnamaldehyde, (E)-cinnamyl alcohol, methyl anisate, vanillin, benzyl isovalerate, benzyl 2-methylbutyrate, methyl eugenol, anisyl aceate, (E)-cinnamyl acetate, 3,4-dimethoxybenzaldehyde, and 4-oxo-α-ionone. \\
