Special Issue Information

Dear Colleagues,

According to the World Health Organization (WHO), as well as numerous scientific research, almost 80% of the world’s population relies on usage of medicinal plants in primary health care. The medicinal importance of these plants and their extracts are closely related to the presence of specific active secondary metabolites (alkaloids, phenolic compounds, flavonoids, terpenes, etc...). Many of these biomolecules can exhibit several pharmacological properties. Hence, herbal extracts often interfere with several animal organs, tissues, cells, and molecular targets, resulting in relieving (or reducing) symptoms of ailments or diseases.

The focusses of this Special Issue are on antioxidant, antimicrobial, and cytotoxic activity of plant extracts. We would like to invite researchers to submit its original scientific results (in the form of manuscripts, reviews, mini-reviews, and short communications) which cover phytochemistry, as well as appropriate pharmacological properties of plant extracts and their major and minor bioactive constituents.

New goals for industry and science have led to increased awareness of food safety and healthier living in the modern era. Here, one of the challenges in food quality assurance is the presence of pathogenic microorganisms. As planktonic cells can form biofilms and go into a sessile state, microorganisms are now more resistant to broad-spectrum antibiotics. Due to their proven antibacterial properties, essential oils represent a potential option to prevent food spoilage in the search for effective natural preservatives. In this study, the chemical profile of Citrus limon essential oil (CLEO) was evaluated. GC-MS analysis revealed that limonene (60.7%), β-pinene (12.6%), and γ-terpinene (10.3%) are common constituents of CLEO, which prompted further research on antibacterial and antibiofilm properties. Minimum inhibitory concentration (MIC) values showed that CLEO generally exhibits acceptable antibacterial properties. In addition, in situ antimicrobial research revealed that vapour-phase CLEO can arrest the growth of Candida and Y. enterocolitica species on specific food models, indicating the potential of CLEO as a preservative. The antibiofilm properties of CLEO were evaluated by MIC assays, crystal violet assays, and MALDI-TOF MS analysis against S. enterica biofilm. The results of the MIC and crystal violet assays showed that CLEO has strong antibiofilm activity. In addition, the data obtained by MALDI-TOF MS investigation showed that CLEO altered the protein profiles of the bacteria studied on glass and stainless-steel surfaces. Our study also found a positive antimicrobial effect of CLEO against S. enterica. The anti-Salmonella activity of CLEO in vacuum-packed sous vide carrot samples was slightly stronger than in controls. These results highlight the advantages of the antibacterial and antibiofilm properties of CLEO, suggesting potential applications in food preservation. Full article
