Antioxidant Activity of Polyphenolic Extracts

Dear Colleagues,

Plant polyphenols are secondary metabolites characterized by one or more hydroxyl groups binding to one or more aromatic rings. Several thousand polyphenolic molecules have been identified in higher plants including edible ones. Plant polyphenols are divided into two major groups, flavonoids and non-flavonoids. Flavonoids can be divided into flavanols, flavonols, anthocyanidins, flavones, flavanones, and chalcones. Non-flavonoids include stilbene, phenolic acids, saponin, and tannins. Among the important biological properties exhibited by plant polyphenols, there has been a great interest in their antioxidant activity. A number of studies have shown that plant polyphenols could be used as antioxidants against different oxidative stress-induced diseases. We invite you to submit your latest research findings or a review article to this Special Issue, which will bring together current research concerning and critical thinking on the antioxidant activity of polyphenolic extracts derived from different natural sources such as terrestrial and marine plants and algae. The identification of the polyphenolic composition of the plant extracts is required for the submitted articles. Your contribution can include both in vitro and in vivo studies relating to different aspects of antioxidant activity of polyphenolic extracts such as structure–activity relationship, the regulation of endogenous antioxidant responses and their role in signaling, metabolism, cell cycle, gene regulation, cellular stress, and the prevention of diseases.

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. Antioxidants 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 2900 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.
