 +"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 [[http://www.thegoodscentscompany.com/data/rw1005071.html|(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." \\ "The essential oil of coriander leaves (Coriandrum sativum) and wild coriander leaves (Eryngium foetidum) grown in Fiji was obtained by steam distillation.
