Special Issue Information

Dear Colleagues,

The first volume of this Special Issue was a great success (https://0-www-mdpi-com.brum.beds.ac.uk/journal/life/special_issues/NaturalProducts_Pharmaceutical); therefore, we invite you to publish your research in the second edition of this Special Issue.

Natural products were the first source of nutritional, pharmaceutical, and cosmeceutical molecules for human health. Notwithstanding the important discoveries made in the field of synthetic (chemical and biotechnological) molecules, natural products still represent an unavoidable source of molecular diversity and are of particular use both on their own and for the creation of novel synthetic compounds. Furthermore, the increasing concern regarding environmental pollution, as well as the awareness that nature is humanity’s ally and should not be challenged by polluting it with molecules not already present in nature, have led to a continuous and steady increase in the consumption of natural and organic products compared to those from new synthetics. A sustainable answer must be given to the question of how to ethically tackle the growing demand for natural products. For these reasons, we believe it is of great importance to develop approaches, molecules, or derived products using an advanced scientific approach that considers traditional usage, but enhancing it in the light of the most advanced technologies available today. Biotechnology approaches that explore “natural equivalent” molecules or up-cycled active principles are most welcome, a sustainable approach toward a paucity-driven approach toward biodiversity.

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. Life 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.

Propolis, a bee product, is known for its variability of chemical and bioactive profiles. However, Portuguese propolis from Gerês, normally obtained by mixing propolis from three places—Bugalho, Felgueiras and Toutelo—has shown similar chemical and biological profiles over the years. Recently, a new propolis place—Roca—was added to the apiary to replace Bugalho, lost to the 2017 wildfires, hence questioning the previously claimed constancy of Gerês propolis. To unravel to what extent the beehive relocation affected this constancy, we studied different Gerês propolis samples collected in three consecutive years (2017–2019) composed of different combinations of source places. Two honey samples, collected before (2017) and after (2018) the occurrence of the wildfire, were also investigated. Total phenolics, flavonoids and ortho-diphenols contents were determined and the antioxidant and antimicrobial activities were evaluated, using the DPPH assay and the agar dilution method, respectively. Although both antimicrobial and antioxidant activities were generally in the ranges usually obtained from Gerês propolis, some variations were detected for the samples, with different compositions when compared to previous years. This work reinforces the importance of the consistency of a combination of several factors for the protection and preservation of the flora near the hives, providing bee products with more constant chemical and biological profiles over the years.
