Wild coriander, spiny coriander, South American cilantro or culantro oil is obtained from Eryngium foetidum L. It possesses a lot of similarity to cilantro oil obtained from the leaves of Coriandrum sativum L.
In addition, trace amounts (< 0.05%) of tridecane, α-copaene, trans-α-bergamotene, germacrene A, cis-linalool oxide-furanoid, (E)-2- tetradecenol, 1-octen-3-ol, linalool, (E)-nerolidol, eugenol, 2-undecanone, β-ionone isomer, (E)-2-decenal and (E)-2-hexadecenal were also found in this oil. Furthermore, the authors found that (E)-2-dodecenal, which was the most abundant component, contributed the greatest odor activity. Other important contributors to the aroma of the oil were eugenol, a trimethylbenzaldehyde isomer, β-ionone, (Z)-4-dodecenal, dodecanal and (E)-2-tetradecenal.
Vietnamese Coriander Leaf Oil
Although no oil is being produced commercially from Vietnamese coriander leaf (cilantro) Persicaria odorata (Lour.) Sojak (syn. Polygonum odoratum Lour.), it is of interest to note the similarities and differences between its volatiles with those of the leaf or herb oil of Coriandrum sativum.
