“…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 this paper was to evaluate the antidiabetic and antioxidant activities of methanolic extracts, n‐hexane, dichloromethane, ethyl acetate, butanol, aqueous subextracts and essential oils of flowers, roots, leaves and aerial parts of Thymbra spicata subsp. spicata, which has been utilized in the public medicine systems of Turkey, Greece, Egypt and Rome for the treatment of asthma and bronchitis, as well as for flavour and aroma in the food industry and protection. Quantitative determination of secondary metabolites in the most effective samples of the plant was also analysed by LC–MS/MS. Moreover, the chemical composition of essential oils of different parts of the plant was analysed via GC‐FID and GC/MS. The main constituents in the flower, leaf and aerial part were found to be carvacrol (75.6%), γ‐terpinene (10.5%), carvacrol (73.3%), γ‐terpinene (9.5%), p‐cymene (8.6%), carvacrol (76.1.8%) and p‐cymene (7.3%), respectively. Quinic acid, caffeic acid, vanillic acid, naringin, hesperidin and rosmarinic acid were measured in four ethyl acetate subextracts, and rosmarinic acid was found to have the highest amount in the flower subextract with a value of 48095.1083 ng/mL. The ethyl acetate extract of flowers showed the best activity with a 326 ± 12 μg/mL IC50 value, while the standard acarbose IC50 value was 4143 ± 243 μg/mL. It was determined that the leaf ethyl acetate extract, in particular, had a very high % inhibition value on ABTS·+ (99.137 ± 0.011% inhibition) and DPPH• (41.068 ± 0.031% inhibition). It is thought that the plant, which has been used as a spice in the kitchen for centuries by the public, can be safely used due to its high antidiabetic and antioxidant effects.
