| The dark blue colored chamazulene is an artifact of the steam distillation of German chamomile flowers. The essential oil collected by steam distillation contained bisabololoxide A (57.6%), chamazulene (23.3%), bisabolonoxide A (4.1%), bisabololoxide B (4.3%), (E)-β-farnesene (2.9%), and germacrene D (1.4%). The fruit esters, ocimenes, artemisia keton and β-selinene were only found in traces. \\ | The dark blue colored chamazulene is an artifact of the steam distillation of German chamomile flowers.

| + | Main volatile compounds of dried chamomile flowers collected with headspace solid-phase microextraction (HS-SPME) were (E)-β-farnesene (49%), artemisia ketone (10.1%), germacrene D (9.1%) and sabinene (7.7%). Interesting minor components not present in the essential oil (steam distillation-solvent extract, SDSE) were e.g. methyl 2-methylbutanoate (0.3%), ethyl 2-methyl butyrate (1.6%), propyl 2-methylbutanoate (0.5%), benzaldehyde (0.5%), and 1,8-cineole (2.2%). Main components of the essential oil were α-bisabolol oxide A (48.0%), chamazulene (20.4%), (E)-β-darnesene (6.7%) and (Z)-spiroether (6.7%). \\ | ||

| In chamomile tea, "...at most only 16% of the genuine essential oil can be extracted by infusion. High amounts of spiro ethers [cis- and trans-enyne-dicycloether] (ca.30% in the infusion vs. ca. 12% in the genuine oil) and coumarins (7%) [namely methylumbelliferone 5.5%] and reduced amounts of bisabolol oxides (ca. 32% in the infusion vs. ca. 60% in the genuine oil) can be regarded as markers of the volatile fraction of chamomile tea." \\ | In chamomile tea, "...at most only 16% of the genuine essential oil can be extracted by infusion.
