Special Issue Information
Dear Colleagues,
The structural variety of natural products is endless. Since the dawn of humanity, nature has provided many molecules that possess beneficial effects; a larger number of these are still utilized to this day. Natural products are a challenge both in their chemical and pharmacological aspects. Due to the complex compositions of extracts, their activity is difficult to investigate. For this reason, the isolation of natural products from complex extracts is of significant importance. More than 70% of all nature-derived extracts studied these days come from plants. Plant metabolism is a complex process, capable of producing primary and secondary metabolites. From a chemical point of view, secondary metabolites are more diverse, but they are found in complex mixtures in extracts. Many secondary metabolites (phenols, flavonoids, triterpenoid saponins) are highly (or poly)-glycosylated. Polar compounds remain a challenge for isolation, even with the use of modern methods and chromatographic sorbents. Their potential as antioxidants is yet to be revealed. These are prerequisites for future drug discovery and product development. This Special Issue aims to publish high-quality articles and reviews, discussing modern, eco-friendly, and practical methods for the extraction, separation, purification, and isolation of natural compounds, particularly those with antioxidant activity.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. 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.
