[54] revealed that p-cymene is an important compound used by the pharmaceutical industries for the production of antioxidants. Tepe B et al. [59] compared the antioxidant activity of two thyme essential oils obtained by hydrodistillation with different chemical compositions. The results showed that the antioxidant activity of the investigated oils is due to the presence of a large amount of thymol and carvacrol in their composition. _Sage_ is represented by the whole or cuts leaves of _Salvia officinalis_ L. Sage essential oil is rich in thujone [63]. It has a very changeable composition depending on the source, time of harvest, and other factors. The antibacterial properties of sage essential oils are due to the presence of thujone, camphor, and 1,8-cineole in the composition [63; 64]. Farhat MB et al. [65] highlighted that the compositions and antioxidant activity of the _Salvia officinalis_ L. essential oils present remarkable differences depending on the environmental conditions and geographical origin. In the study conducted by Ozan A et al. [66] on various essential oils from wild and cultivated forms of _Salvia pisidica_ it was shown that the antioxidant properties are due to the \(\alpha\)-pinene, camphor, and eucalyptpol compounds present in the composition of the investigated oils. The results are in accordance with the results reported by Ruberto et al. [67]. _The funnel_ plant belongs to the family _Apiaxene (Lmbellifene)_. According to Masada et al. [68; 69], the ripening stages play an important factor in influencing the composition of essential oils, while good agricultural and environmental practices would also help to improve yield and quality. The main constituents of essential oils are: anethole (72.27%-74.18%), fenchone (11.32%-16.35%), and methyl chavicol (3.78%-5.29%), followed by \(\alpha\)-pinene, limoneene, \(\beta\)-myrrene, camphene, \(\beta\)-pinene, 3-hull, \(\alpha\)-phellandrene, cis-anethole, camphor, 1,8-cineole [70]. Fennel oil contains powerful anti-inflammatory compounds, which, when used topically, help with skin care. In a study conducted by Anwar et al. [71], the antioxidant and antimicrobial activities of essential oil, ethanol, and methanol extracts of fennel (_Foeniculum vulgare Mill._) seeds were examined. The results obtained demonstrate good antioxidant and free radical scavenging activities as well as appreciable antimicrobial activity against selected strains of bacteria and pathogenic fungi for essential oil and various extracts from fennel. _Eucalyptus_ (_Eucalyptus_ spp.) is a plant native to Australia grown mainly as a source of fast-growing wood, as well as a source of essential oil used for many purposes. The essential oil is extracted from buds, leaves, bark, and fruits, having an antiseptic, antibacterial, anti-inflammatory, antioxidant, and anticancer action and, therefore, is recommended in the treatment of respiratory diseases like flu, colds, and sinus congestion [72]. The composition of the eucalyptus oil is influenced by geographical location or seasons, which also influences its biological activity. The main compounds of the essential oil are eucalyptpol, p-cymene, neo-isoverbenol, limone, and spathulenol (depending on the species) [73; 74; 75]. Salem et al. [76] studied the antioxidant activities of the essential oil from the leaves of _Eucalyptus camaldulensis_, _Eucalyptus camaldulensis_ and _Eucalyptus gomphocenphala_. It was found that the essential oil of _Eucalyptus gomphocenphala_ presented the highest antioxidant activity. The study reported that the antioxidant activities of eucalyptus essential oil could be related to phenols such as spathulenol and terpen such as eucalyptpol (1,8-cineole). _Pine_ (_Pinaceae_), is one of the most important sources of essential oils in the world, with more than 50 constituents, of which about ten are of key importance [77].
