“…Hyssopus officinalis L. ( Lamiaceae ) grows in large numbers on dry, stony, calcareous soils in Europe and Southwest and Central Asia. On the territory of Russia, it is found only in the Far East [ 81 , 82 ]. Health-preserving properties of hyssop are due to the richness and variety of secondary metabolites of their extracts [ 82 ].…”

The development of new effective anti-coronavirus drugs and therapies is important, but it requires significant human, financial and, most importantly, time expenditures. The current pandemic is neither the first nor the last. Humanity has already accumulated considerable survival experience. We cannot do without prevention and epidemiological protection measures. This study reviews medicinal plants that grow in Northeast Asia and whose antioxidant, antiviral, anti-inflammatory and immunomodulatory characteristics are already known, also in the framework of the prevention and treatment of pneumonia of various etiologies. The need for a comprehensive approach to maintaining immunodefences, including functional foods and positive emotions, is emphasized. In the period of pandemics, it is important to research various areas that allow to us accumulate a critical mass of information and cope with the next global disease.

“…The highest EO yield at the flowering stage is a usual phenomenon observed in many MAPs, in particular with those belonging to the Lamiaceae family [34,35]. This can be explained as an outcome of enhanced photosynthetic activity during flowering which boosts the growth of glandular trichomes [36] and biosynthesis of secondary metabolites compared to vegetative and post-flowering stages [35].…”

“…Therefore, the employment of multiple methods to evaluate the antioxidant activity can give increasing information on their antioxidant properties [61,62]. The different behavior of EOs in various methods can represent the oxidant/antioxidant models and or lipophilic/hydrophilic properties of the EOs' components [36]. The DPPH assay was used to estimate the radical scavenging activity of EOs [63].…”

“…In the ABTS assay we observed different results with respect to the DDPH assay, with the best activity being displayed by the EO samples obtained at fruiting and flowering (Table 3). This difference in the antioxidant activity can be related to different mechanisms of the antioxidant reactions in the assays, the stereoselectivity of the radicals and differential solubility of EO constituents [36]. Notably, the EO obtained at fruiting contained the highest amount of the highly hydrophobic p-cymene (14.7%) ( Table 3) that may contribute to boosting the activity of this sample due to its documented efficacy as an antioxidant agent [63].…”

“…EOs at the flowering stage. The antioxidant activity of S. macrantha EOs is linked to the presence of the phenolic monoterpenes thymol and carvacrol and their precursor p-cymene which are able to scavenge different radical [36,53,68]. The highest antioxidant activity of the EO from the flowering stage is related to the concomitant presence of thymol and carvacrol which can act synergistically as radical scavengers [69] due to the presence of hydroxyl groups in their structures [70].…”

Essential oils (EOs) from medicinal and aromatic plants are interesting products to be used as natural food preservatives. The EOs from the genus Satureja are reported to inhibit foodborne pathogens being worthy of use as food preservatives. Satureja macrantha is found in Western and Northwest Iran and commonly used as a food flavoring agent and for the treatment of urinary diseases. The objective of the present study was to identify the chemical composition of S. macrantha EOs at different growth stages (vegetative, flowering and fruiting stages) and to evaluate their biological activities. Chemical compositions were analyzed using GC-FID and GC-MS. The antibacterial activity was evaluated using the broth microdilution method against the foodborne pathogenic bacteria Staphylococcus aureus (ATCC23922), Enterococcus faecalis (ATCC29212) (Gram-positive), Enterobacter aerogenes (ATCC13046) and Escherichia coli. The antioxidant activity was estimated using the DPPH, ABTS and reducing power assays. The yields of S. macrantha EOs were in the range of 1.4–1.8%, thus scalable for the manufacture of food preservatives on an industrial level. The main compounds of EOs were carvacrol (42.7–48.2%), thymol (0.2–16.5%), p-cymene (10.1–14.7%) and γ-terpinene (7.9–9.1%) in all phenological stages examined. The strongest antibacterial activity (MICs = 5–20 µg/mL) of the EOs was recorded in samples obtained during the flowering stage where carvacrol (42.7%) and thymol (16.5) were present both at high percentages. On the other hand, the antioxidant activity was found to be slightly higher in the other stages. As the EO obtained at flowering showed the best inhibitory properties against foodborne pathogenic bacteria, it is suggested that plants at this stage can be selected as main sources of food preservative agents.

The aim of the present study was a chemical, microbiological and statistics analysis of Hyssopus officinalis L. subsp. aristatus (Godr.) Nyman essential oil during different stages of development from three natural populations of plant collected in southeastern Serbia. In addition, using statistical tools, we also tried to explain the effect of dominant componentsˈ content on antimicrobial activity. Oxygenated monoterpenes were the most abundant compound class in the H. officinalis oil during examined phenological stages (27.32‐92.25%). The four most abundant essential oil components are eucalyptol, cis‐pinocamphone, β‐pinene and β‐ocimene. H. officinalis essential oils demonstrated minimum inhibitory concentrations and minimum microbicidal concentrations values from 2.4 to 160 mg/mL. Maximum antimicrobial activity, in total, was recorded in November, after the flowering stage. The percentage of dominant compounds of essential oils, eucalyptol, and cis‐pinocamphone, affects essential oils' antibacterial activity. The essential oil with most closely matched research criteria was extracted from a plant in Kravlje village.
