“…The principal constituents in the essential oil from T. vulgaris were thymol, ρ ‐cymene, and carvacrol (Table 1); those in the essential oil from S. officinalis were camphor, β‐pinene, and 1,8‐cineole; and those in the essential oil from O. basilicum were ( E )‐anethole, linalool, and 1,8‐cineole. Similar to the results obtained in the present study, Zanotto et al (2023) found thymol (45.95%) as the principal constituent in the essential oil from T. vulgaris , followed by ρ ‐cymene (25.11%). Liu et al (2021) observed that thymol (26.18%) was the principal constituent found in the essential oil from T. vulgaris , followed by 1,3,8‐ p ‐menthatriene (25.16%), limonene (12.37%), α‐pinene (8.47%) and α‐terpineol (4.92%).…”

The essential oils from Thymus vulgaris, Salvia officinalis, and Ocimum basilicum were extracted by hydrodistillation, characterized by gas chromatography/mass spectrometry, and quantified by gas chromatography/flame ionization detector. The principal constituents were thymol, ρ‐cymene and carvacrol (T. vulgaris); camphor, β‐pinene, and 1,8‐cineole (S. officinalis); and (E)‐anethole, linalool, and 1,8‐cineole (O. basilicum). The essential oil from T. vulgaris was the most effective, forming inhibition halos of 46.16 ± 0.16 and 26.38 ± 0.33 mm, respectively, for Salmonella choleraesuis and Listeria monocytogenes. This essential oil was also more effective against S. choleraesuis, with a minimum inhibitory concentration of 8.85 mg mL−1, and a minimum inhibitory concentration of 17.71 mg mL−1 for L. monocytogenes. No bactericidal activity against S. choleraesuis and L. monocytogenes was observed for the essential oils from S. officinalis, and O. basilicum. Scanning electron micrographs showed that the addition of essential oils left the bacterial cells damaged and deformed. Significant 2,2‐diphenyl‐1‐picrylhydrazyl free radical scavenging capacity and lipid substrate protection were observed in the β‐carotene bleaching assay for the essential oil from T. vulgaris, with IC50 of 231.13 ± 0.53 and 15.25 ± 0.38 μg mL−1, respectively. A dose‐dependent relationship between antioxidant activity and concentrations was observed in the tests. Toxicities of LC50 = 1.24, 3.51 and 1.19 mg mL−1 against Drosophila suzukii flies, respectively, were observed for the essential oils from T. vulgaris, S. officinalis, and O. basilicum. Results suggest that essential oils can be promising antioxidant agents, insecticides, and inhibitors of pathogenic bacteria.

“…O. vulgare , T. vulgaris , and T. serpyllum presented the highest antifungal activity of all the tested EOs. This is again in accordance with previous research that showed their strong inhibitory effects ( Paris et al., 2020 ; Pinto et al., 2020 : Yan et al., 2021 ; Di Francesco et al., 2022 ; Elsayed et al., 2022 ; Kara et al., 2022 ; Zanotto et al., 2023 ). The commercial mixture of M. alternifolia , O. vulgare , C. zeylanicum and T. vulgaris presented quite high inhibitory activity, although this was lower than that of the most active of its components ( O. vulgare ), similar to that of T. vulgaris , but stronger than that of M. alternifolia and C. zeylanicum .…”

Gray mold and brown rot, caused respectively by Botrytis cinerea and Monilinia spp., are fungal diseases responsible for significant losses during the storage of fruit and vegetables. Nowadays, the control of postharvest diseases is shifting towards more sustainable strategies, including the use of plant secondary metabolites. In this study, the antifungal activity of Origanum vulgare, Thymus vulgaris, Thymus serpyllum, Melaleuca alternifolia, Lavandula officinalis, Lavandula hybrida, Citrus bergamia, Rosmarinus officinalis, Cinnamomum zeylanicum essential oils (EOs) in vapor phase was tested in vitro against B. cinerea, Monilinia fructicola, Monilinia fructigena, and Monilinia laxa. For the experiments, a protocol using a volatile organic compounds (VOC) chamber was designed. Results indicate a dose-dependent inhibitory activity of all the tested EOs, with O. vulgare, T. vulgaris, and T. serpyllum being the most active ones, with minimum inhibitory concentrations (MIC) of 22.73, 45.45, and 22.73 µl/L, respectively, against B. cinerea and a range between 5.64 and 22.73 µl/L against the three Monilinia spp. Overall, B. cinerea presented lower sensitivity to vapor-phase EOs than any of the Monilinia strains, except for the C. zeylanicum EO, which consistently showed higher inhibition against B. cinerea. Among the three Monilinia spp., M. fructicola was the least sensitive, while M. fructigena was the most sensitive. The use of VOC chambers proved to be a reliable protocol for the assessment of antimicrobial activities of EOs. These results suggest that the VOC emitted by the tested EOs are effective towards important decay-causing fungi, and that they could be used for the control of gray mold and brown rot in in vivo trials.

“…Zanotto et al ( 2023) [61] evaluated the effect of MELs in essential oil activity stabilization and solubilization. Essential oils are natural and effective agents for controlling microorganisms that cause biodeterioration and disease, and therefore are good alternatives to chemical food preservatives.…”

Mannosylerythritol lipids (MELs), one of the most promising biosurfactants (BS), are glycolipids produced by yeasts or fungi, which have great environmental performance and high compatibility with the human body. MELs, besides working as typical surfactants, can form diverse structures when at or above the critical aggregation concentration (CAC), reduce the surface tension of water and other solutions, and be stable over a wide range of conditions. Among others, MELs present antimicrobial, antitumor, antioxidant and anti-inflammatory activities and skin and hair repair capacity, which opens possibilities for their use in applications from cosmetics and pharmaceutics to bioremediation and agriculture. However, their market share is still low when compared to other glycolipids, due to their less developed production process and higher production cost. This review gathers information on the potential applications of MELs mentioned in the literature since 1993. Furthermore, it also explores the current strategies being developed to enhance the market presence of MELs, in parallel with the ones developed for rhamnolipids and sophorolipids.
