“…Brandão et al (2022) studied the essential oil from O. basilicum and observed that the principal constituents were linalool (26.89%), 1,8‐cineole (23.62%), and camphor (15.69%). At the same time, Alimi et al (2022) reported that trazole (80.87%) and linalool (16.12%) were the main constituents of the essential oil from O. basilicum , with a yield of 0.24%.…”

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.

“…Moreover, the materials also showed efficacy against S. aureus and P. aeruginosa bacteria strains. Recently, EOs from Ocinum basilicum and Ocinum gratissinum were successfully encapsulated into PLA nanofibers by blow spinning method [ 87 ]. By mixing different proportions of the mentioned EOs, it allowed the bioactive materials to display effectiveness as an antifungal against Aspergillus ochraceus and Aspergillus westerdjikiae .…”

Antimicrobial resistance (AMR) developed by microorganisms is considered one of the most critical public health issues worldwide. This problem is affecting the lives of millions of people and needs to be addressed promptly. Mainly, antibiotics are the substances that contribute to AMR in various strains of bacteria and other microorganisms, leading to infectious diseases that cannot be effectively treated. To avoid the use of antibiotics and similar drugs, several approaches have gained attention in the fields of materials science and engineering as well as pharmaceutics over the past five years. Our focus lies on the design and manufacture of polymeric-based materials capable of incorporating antimicrobial agents excluding the aforementioned substances. In this sense, two of the emerging techniques for materials fabrication, namely, electrospinning and 3D printing, have gained significant attraction. In this article, we provide a summary of the most important findings that contribute to the development of antimicrobial systems using these technologies to incorporate various types of nanomaterials, organic molecules, or natural compounds with the required property. Furthermore, we discuss and consider the challenges that lie ahead in this research field for the coming years.
