Special Issue Information

Dear Colleagues,

Australia and New Zealand are ideal locations for research into natural products of both terrestrial and marine origin. Due to their geographic isolation, both have unique flora and fauna and a very high degree of endemism in that biota. For example, 92% of Australia’s and 80% of New Zealand’s vascular plants are endemic. Both countries have extensive coastlines, a wide variety of marine habitats and very large exclusive economic zones and endemism in the oceans of the region is also at a high level.

Not surprisingly therefore, natural products research of all kinds is very active in this area. For example, Marinlit, a database of the marine natural products literature contains 155 records for studies pertaining to organisms collected from New Zealand waters and 713 records for organisms from Australian waters between the years 1970 and 2015. Natural product research in the region is diverse, encompassing fields, such as biodiscovery, chemical ecology, synthesis, environmental impact studies and many others.

As Guest Editor, I invite researchers to submit their work relevant to these topics and to any others encompassing natural products research in the region to this Special Issue of Molecules. The aim of this issue is to showcase the breadth and quality of natural products research in this part of the globe.

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 papers will be 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. Molecules 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 1800 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.

The study was based on the use of a toothpaste with antiphlogistic activity, containing Australian Melaleuca alternifolia oil (tea tree oil—TTO) and ethanolic extract of Polish propolis (EEP). Fifty-one patients with varying conditions of the gingiva were divided into two groups. The study group received the toothpaste with TTO and EEP, while the control group received the same toothpaste but without TTO and EEP. Approximal plaque index (API), simplified oral hygiene index (OHI-s) and modified sulcus bleeding index (mSBI) were assessed in three subsequent stages. During each examination, swabs were employed for microbiological inoculation. During the period of use of toothpastes with TTO and EEP, a significant reduction of the API was observed, as assessed upon the control visit after 7 days and after 28 days, compared to baseline. A statistically significant reduction of mSBI was observed after 7 and 28 days of using the toothpaste with TTO and EEP, as compared to the value upon the initial visit. Statistically significant differences in the OHI-s value were observed in the study group, which was using the active toothpaste. The use of a toothpaste containing TTO and EEP helps to maintain microbiome balance. The observed stabilisation of bacterial microflora confirms the beneficial activity of toothpaste containing EEP and TTO compared to the control group, where the lack of these substances contributed to the emergence of qualitative and quantitative changes in oral microbiome.
