Main constituents
The essential oil from the leaves of long coriander is rich in aliphatic aldehydes, most of which are α,β unsaturated. The impact compound is E-2-dodecenal (60%), furthermore 2,3,6-trimethylbenzaldehyde (10%), dodecanal (7%) and E-2-tridecenal (5%) have been identified. Aliphatic aldehydes appear also in other spices with coriander-like scent (e. g., Vietnamese coriander).
Yet another essential oil can be obtained from the root; in the root oil, unsaturated alicyclic or aromatic aldehydes dominate (2,3,6-trimethylbenzaldehyde 40%, 2-formyl 1,1,5-trimethyl cyclohexa-2,5-dien-4-ol 10%, 2-formyl 1,1,5-trimethyl cyclohexa-2,4-dien-6-ol 20%, 2,3,4-trimethylbenzaldehyde).
In the essential oil from the seeds, sesquiterpenoids (carotol 20%, β-farnesene 10%), phenylpropanoids (anethole) and monoterpenes (α-pinene) were found, but no aldehydes.
