“…In general, for complex systems such as essential oils, using at least three methods with different mechanisms is preferable and in some cases required to evaluate antioxidant activities. The DPPH • and ABTS •+ assays are efficient tools for the determination of antioxidant activity; although these methods have an identical mechanism, the mediums for the assay are different which means there is a dissimilar solubility of the isolated bioactive compounds [ 60 ]. The SOA, like ABTS •+ assay, share the water medium, but at a different pH level.…”

Steam distillation was used for the isolation of Dracocephalum moldavica L. (Moldavian dragonhead) essential oil (DMEO). This aromatic herbaceous plant is widespread across the Northern Hemisphere regions and has been utilized in health-improving studies and applications. In addition to the DMEO, the hydrolate (DMH), a byproduct of the distillation process, was also collected. The DMEO and DMH were analyzed and compared in terms of their chemical composition, as well as their in vitro biological activities. The main component in DMEO was geranyl acetate, while geranial was dominant in DMH. The DMEO demonstrated better antioxidant and antimicrobial activities compared with the DMH against Staphylococcus aureus, Escherichia coli, Salmonella Typhimurium, and Listeria monocytogenes, which represent sources of food-borne illness at the global level. The DMEO and DMH show promise as antioxidant and antimicrobial additives to various products.

“…Based on the results presented in Figure 2 , the ABTS assay showed higher activity than those for the DPPH assay regarding the identical principles that these two assays represent. A study using S. kitaibelii showed that the medium for the assay had a crucial impact on the solubility and availability of the extracted compounds [ 58 ]. The reducing power varied from 0.1 μmol TE/g for HY to 369.31 μmol TE/g for SWE of S. montana subsp.…”

“…The subcritical water extraction of S. montana was performed in a home-built subcritical water extractor as described previously [ 58 ], maintaining a sample-to-solvent ratio of 1:30 in all extractions. The pressurization of the extraction vessel to 20 bars was performed with 99.999% nitrogen (Messer, Germany).…”

Winter savory (Satureja montana L.) is a well-known spice and medicinal plant with a wide range of activities and applications. Two subspecies of S. montana, subsp. montana and subsp. variegata, were used for the preparation of seven different extracts: steam distillation (essential oil (EO) and hydrolate (HY)), subcritical water (SWE), ultrasound-assisted (UAE-MeOH and UAE-H2O), and microwave-assisted (MAE-MeOH and MAE-H2O) extraction. The obtained EOs, HYs, and extracts were used for an in vitro evaluation of the antioxidant activity (DPPH, ABTS, reducing power, and superoxide anion methods) and in vitro antimicrobial activity against Bacillus cereus, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Salmonella Typhimurium, Saccharomyces cerevisiae, and Candida albicans. The antimicrobial screening was conducted using disk-diffusion assessment, minimal inhibitory concentration, time–kill kinetics modeling, and pharmacodynamic study of the biocide effect. The total phenolic content (TPC) was highest in EO, followed by SWE, MAE, and UAE, and the lowest was in HY. The highest antimicrobial activity shows EO and SWE for both varieties, while different UAE and MAE extracts have not exhibited antimicrobial activity. The natural antimicrobials in the S. montana extract samples obtained by green extraction methods, indicated the possibility of ecologically and economically better solutions for future in vivo application of the selected plant subspecies.

“…In order to assess of antimicrobial activity of pure essential oil, the disk-diffusion method reported in detail by Riabov et al 30 In order to evaluate the pharmacodynamic potential of the antimicrobial effect of the determined MICs, the time-kill study was done. Aćimović et al 32 have described in detail time-based monitoring of the antimicrobial effect of MICs during contact with sensitive microorganisms.…”
