Table 4: _Cont._chamomile oil in the following amounts: 8%, 6%, and 3.9%; and approx. 3%, 3%, and 4-18% [17; 18; 20]. According to the literature, \(\alpha\)-bisabolol and chamazulene detected in chamomile essential oil have antimicrobial properties. Both of these compounds also have anti-inflammatory properties, and chamazulene also exhibits anti-allergic activity [21]. Accordingly, chamomile oil is a potentially biologically active substance and can be used to investigate its possibility to be released from the model insert. The total amount of released compounds in the gas phase of cellulose agar media with chamomile essential oil is presented in Table 5. For each of the inserts with essential oil, the main compounds were identified and recorded after the specified incubation time. As the inserts were stored in the model systems, a reduction in the number of compounds in the headspace phase of the matrix was observed. Crystalline cellulose is not largely affected by the environmental moisture in comparison to, e.g., hemicellulose [30], which is beneficial to keep its performance in combination with other materials [31]. Figure 4: Chromatogram of chamomile essential oil (GC–MS); main compounds: 1—\(\beta\)-farnesene; 2—a-bisabolone oxide A; 3—a-bisabolol; 4—chamazulene; 5—a-bisabolol oxide A; and 6—cis-ene-yne-Dicycloether.
