Plant Natural Products: Extraction and Antioxidant Activity

Dear Colleagues,

Natural products continue to provide an exceptional reservoir of bioactive compounds with roles in redox regulation and enzymatic control. Growing interest in plant-derived antioxidants and inhibitors of oxidative enzymes has intensified research on their mechanisms, ecological functions, and potential applications in health, agriculture, food, and biotechnology. This Special Issue focuses on natural products or plant extracts with demonstrated antioxidant activity or inhibitory effects on oxidative enzymes such as oxidases, peroxidases, lipoxygenases, and other redox-driven catalytic systems. We welcome contributions that combine phytochemical characterization, isolation of natural compounds, chromatographic or spectroscopic profiling, bioassay-guided studies, enzyme inhibition assays, mechanistic evaluations, and computational or molecular approaches. Submissions addressing structure–activity relationships, quantification of bioactivity, synergistic interactions within characterized complex matrices, or advances in analytical and bioautographic methods are particularly encouraged. Research on underexplored species, sustainable sourcing, and innovative or green extraction technologies also fits within the scope. Both original research articles and well-structured review papers are invited. By bringing together high-quality studies, this Special Issue aims to highlight current progress and future opportunities in understanding and harnessing plant-derived antioxidants and oxidative enzyme inhibitors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
