Secondary Metabolites from Natural Products: Extraction, Isolation and Biological Activities, 2nd Edition

Dear Colleagues,

Building on the success of the first edition, we are pleased to launch the 2nd Edition of the Special Issue, “Secondary Metabolites from Natural Products: Extraction, Isolation and Biological Activities”. This Special Issue is dedicated to unlocking the potential of compounds found in nature and to showcasing the broad scientific landscape of natural products and secondary metabolites.

This Special Issue welcomes manuscripts covering a wide thematic spectrum, from the discovery and sourcing of natural materials to the development of knowledge and applications. Studies may involve compounds originating from plants, fungi, lichens, microorganisms, marine organisms, and other natural reservoirs, as well as natural product-related processes and transformations. Secondary plant metabolites remain an important focus, while contributions from any natural source are equally encouraged.

We invite submissions addressing, including but not limited to, extraction and separation (classical and emerging), isolation and purification, chemical profiling and structure elucidation, analytical and computational approaches, bioactivity screening and functional evaluation, modes of action, safety and quality aspects, and pathways toward practical use. Relevant application areas include medicine and pharmacotherapy, agriculture and crop protection, food technology and functional foods, nutraceuticals, cosmetics, materials, and environmentally friendly technologies—along with studies aligned with sustainability, green chemistry, biodiversity preservation, and responsible use of natural resources.

As an interdisciplinary topic, this Special Issue bridges chemistry, biology, pharmacology, biotechnology, food and agricultural sciences, and environmental research, fostering collaboration among experts from various domains and encouraging both fundamental and applied contributions. We welcome original research articles, reviews, and short communications that advance the field and open new directions for natural product research.

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. Molecules 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.
