Biological and Toxicological Activities of Plant Extracts and Their Extraction Methods

Dear Colleagues,

Biological species, from prokaryotes to higher plants, that inhabit all kinds of terrestrial, freshwater, marine and extreme environments have been, for thousands of years, the main source of natural compounds.

Nowadays, natural products are increasingly receiving more attention from the scientific community, not only because they may pose less risks than their synthetic equivalents, but also because they are a part of the vast majority of agro-industrial wastes (food processing, agricultural residues, forestry logging operations, etc.). Thus, their valorization is seen as a stepping stone toward a more sustainable approach for the further development of scientific progress, industry and economic growth.

With that in mind, this Special Issue is dedicated to toxicological activities (contact toxicity, anti-feeding, repellency, fumigation, molluscicidal, etc.) and biological activities (antioxidant, antibacterial, antifungal, anti-inflammatory, antiobesity, anti-acetylcholinesterase, etc.) of extracts derived from all kinds of terrestrial or marine species, as well as agro-industrial wastes.

We will accept works employing innovative and green extraction/isolation methodologies; bioassay-guided approaches are much appreciated, but classical extraction methods may be included.

We look forward to your contributions.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly 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 2600 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.
