Table 6: Summary of the composition of the gas phase of matrices with chamomile EO and cellulose or microcrystalline cellulose during storage and comparing it with the chemical composition of chamomile essential oil (blue font indicates compounds where their presence was found in all types of matrices). On the day of preparing the inserts, in the gas phase, the following compounds were found above all matrices: artemisia ketone, \(\alpha\)-farnesene, \(\beta\)-farnesene, \(\beta\)-caryophyllene, bicyclogermacrene, \(\delta\)-adinene, \(\alpha\)-bisabolol, chamazulene, and \(\alpha\)-bisabolone oxide. Of these compounds, bicyclogermacrene, \(\delta\)-adinene, and \(\alpha\)-bisabolone oxide were not detected in chamomile essential oil because they were probably outside the detection and quantification range of the used method. The oil also did not contain \(\alpha\)-caryophyllene (detected in EO:C 1:1 and 1:3, and EO:CM 1:1 and 1:2), 7-epi-1,2-dehydrosequicneol, and \(\alpha\)-amorphene (present in EO:C 1:2 and 1:3, and EO:CM 1:2). The main compound was \(\beta\)-farnesene, ranging from 64.62 to 68.58%. It was also one of the main chemical compounds in pure essential oil (19.39%). In the gas phase above the surface of the insert, there were compounds which were not detected in chamomile essential oil: \(\alpha\)-caryophyllene, 7-epi-dehydrosequicineol, \(\alpha\)-amorphene, germacrene D, bicyclogermacrene, \(\delta\)-adinene, \(\alpha\)-bisabolone oxide A, and \(\alpha\)-bisabolol A oxide.
