Table 1: _Cont._due to low share of this compound in the present study Besides, \(o\)-cymene shows anti-viral effect against the virus of human influenza H1N1 [63; 64; 65; 66; 67]. In the case of limonene, eucalypt, \(\beta\)-linalool and thymol the difference was observed between BA and IAA cultures, in favor for BA ones--the share of listed volatiles were higher. First of them -limonene is the most important volatile obtained from citrus peels essential oils, in which the content of limonene can reach as much as 97-98%. Limonene has been reported to control the development of _S. aureus_. What is more, in pre-clinical investigations this compound was revealed to have an inhibitory effect on the development of cancers, including the melanoma. Studies in vitro yield similar results. Limonene is characterized by anti-viral activity against the bird flu virus HSN1 type A and against COVID-19. At present it is possible to acquire limonene from citrus wastes [68; 69; 70; 71; 72; 73]. Moreover, _C. reticulata_ leaf essential oil from cultivars Cara mandarin, Kishu mandarin and Willow leaf mandarin--whose one of the main components is d-limonene--was reported to have a promising inhibitory impact on the tested aging enzymes [74]. Furthermore, eucalypt is a component of the essential oil of a few eucalyptus species, i.e., _E. longicornis_ (84.2%), _E. vandoo_ (73.6%), _E. Lesouefi_ (40.8%). The essential oils from eucalyptues are reported as highly effective in controlling the adhesion by gram-negative (_Pseudomonas aeruginosa, Escherichia coli_ and _Acinetobacter baumanmii_) and gram-positive (_Staphylococcus aureus_ and _Listeria monocytogenes_) bacteria. Eucalyptus oil displays also anti-inflammatory quality and anti-viral activity, e.g., against influenza A (H1N1) virus. Besides, this oil can potentially act as an Mpro inhibitor of COVID-19. What is more, it has been found to show phytotoxicity to _Sinapis arrensis_ and _Raphanus sativus_[75; 76; 77; 78; 79; 80; 81]. Eucalypt alone belongs to compounds having a potential for treatment of influenza [82]. Another compound, which is present plentifully in the aroma profile of two night-blooming species representing the genus Silene (_Caryophyllaceae_), namely _S. chlorantha_ (40.5%) and _S. italica_ (14.5%), is \(\beta\)-linalool. It is also present in _Osmanthus fragrans_ var. thunbergi (27.71%) [83; 84] and cardamom (0.44-11.0%) [85]. And this is mainly linalool that is responsible for the fragrance of the lychee fruit [86]. This compound, also one of the basic components of _Citrus retictal_ leaves essential oil, possesses promising attributes as an additive to anti-aging cosme for skin care [74]. Fumigation with linalool hinders significantly the growth of _Botrytis cinerea_ mycelium and expansion of this pathogen on tomato fruit [87]. Thymol is the main component of essential oils emitted by plants falling within the family _Lamiaceae_. In _Thymus vulgaris_ L. essential oil the percentage of this compound ranges from 10 to 64%.
