-"The volatile oils isolated by steam distillation from the leaves and roots of Eryngium foetidum were analyzed by capillary GC, GC/MS and 1H-NMR. Alkanals and alkenals constituted the main chemical category in the leaf oil which contained (E)-2-dodecenal as the most abundant component (59.72%). In contrast, the root oil contained high amounts of aromatic and terpene aldehydes, among which 2,3,6-trimethylbenzaldehyde (37.55%) and 2-formyl-1,1,5-trimethylcyclohexa-2,4-dien-6-ol (19.82%) predominated." \\

 "The essential oil of coriander leaves (Coriandrum sativum) and wild coriander leaves (Eryngium foetidum) grown in Fiji was obtained by steam distillation. The aroma profiles were characterised using gas chromatography-olfactometry (GCO) and CharmAnalysisTM. The character-impact odorants were identified using comprehensive two-dimensional gas chromatography (GC×GC) combined with time-of-flight mass spectrometry (TOFMS). During GCO analysis, the co-elution of E-2-alkenals and E-2-alken-1-ols resulted in the perception of ‘odour-clusters’... The most abundant compound in E. foetidum was E-2-dodecenal (63.5% TIC), which also contributed the most odour activity (52.9%). Other important odorants were either eugenol or a trimethylbenzaldehyde isomer, β-ionone, Z-4-dodecenal, dodecanal, and E-2-tetradecenal. GC×GC–TOFMS allowed the identification of... 20 compounds not previously reported in the literature for... E. foetidum... In particular, β-ionone was determined to be an important odorant in both samples but could not be identified with GC–qMS." \\
