Information for Authors
Guidelines for authors
Free Radicals and Antioxidants [ISSN: 2231-2536] is an online peer reviewed publication dedicated to publishing novel, original findings in the field of free radical biology and both natural and synthetic antioxidants. Free radicals, which are defined as molecules containing one or more unpaired electrons in their outmost atomic or molecular orbital have emerged as double edged swords. Recent research has revealed that they can be both beneficial (e.g. in microbicidal activity inside neutrophils) or deleterious (e.g. lipid peroxidation and membrane damage). Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are the two major classes of free radicals. The generation of these reactive species is tightly controlled by enzymes like nitric oxide synthase (NOS) and NAD (P)H oxidase. Mechanisms exist inside cells that both generate and protect against ROS-induced oxidative damage. This equilibrium termed as “redox homeostasis” is vital for the health and continued survival of the cell. The Free Radicals and Antioxidants Journal aims to foster the dissemination of scientific information by publishing manuscripts that provide new insights into the biology of free radicals, including their generation, degradation, modulation, role in cellular function and cell signaling. The submission of uninvited expert reviews and research articles in all areas of Free Radical Biology and Antioxidants are also welcomed. Free Radicals and Antioxidants publishes full research papers presenting original, high-quality research, critical review articles providing a comprehensive analysis of research development within a defined area and editorial commentaries on key topical issues in Free Radical and Antioxidant Biology.

Preparation of Manuscript
The manuscript should be typed, double-spaced on standard-sized – paper (8.5" x 11") with 1" margins on all sides. Times New Roman font 12 pt should be used. The fonts used in the text, as well as graphics, should be restricted to Times New Roman, Symbol and Zapf Dingbats.
A research paper typically should include the following in the order given below :
- Materials and Methods
- Results including Tables and/or Figures
- Acknowledgements (If any)
- Appendixes (if necessary)
- Abbreviations used (if necessary)
Should be in Title Case; The first character in each word in the title has to be capitalized. Authors’ names and affiliations should not be given.
Should be structured and limited to 250 Words. A brief summary of the research should be given under the subheadings Introduction, Methods, Results, and Conclusions..
No more than six keywords are needed. Words appearing in the title should not be given as keywords. It is desirable to include the alternative words, if any under keywords e.g. the word ‘epinephrine’. They should be written left aligned, arranged alphabetically in 12pt Times Roman, and the line must begin with the words Keywords boldfaced. A 12pt space should separate the keywords from the affiliations.
Description of the research area, pertinent background information, and the hypotheses tested in the study should be included under this section. The introduction should provide sufficient background information such that a scientifically literate reader can understand and appreciate the work to be described. A detailed review of the literature is not at all required under this section. The specific aims of the project should be identified along with rationale for the specific experiments and other work performed. The introduction MUST include in-text citations including a few references pertinent to the background and justification for the study.
Materials and Methods
Materials and/or subjects utilized in the study as well as the procedures undertaken to complete the work. The methods should be described in sufficient detail such that they could be repeated by a competent researcher. The sources of all major instruments and reagents used (kits, drugs, etc) must be given with parentheses. Illustrations and/or tables may be helpful in describing complex equipment or elaborate procedures. The statistical tool used to analyze the data should be mentioned. All procedures involving experimental animals or human subjects must accompany a statement on ethical approval from appropriate ethics committee.
Data acquired from the research with appropriate statistical analysis described in the methods section should be included in this section. The results section should highlight the important results obtained. Data should be organized into figures and tables. Qualitative as well as quantitative results should be included if applicable.
This section should relate the results section to current understanding of the scientific problems being investigated in the field. Description of relevant references to other work/s in the field should be included here. This section also allows the author to discuss the significance of the results - i.e. does the data support the hypotheses you set out to test? This section should end with new answers/questions that arise as a result of the author’s work.
Tables and Figures
Tables should be numbered with Roman numerals according to their sequence in the text, and have a short self-explanatory heading. Use SI units. Tables should include vertical rules, but horizontal rules should separate column headings from the content. Authors should keep in mind the page layout of the journal when designing tables. Tables that fit onto one printed page are preferred. Detailed explanations of symbols, units, and abbreviations should be given below the table.
Figures for final production should be submitted as electronic files and hard copy so that the editorial office can ensure that the output of electronic files matches the hardcopy. Please pay particular attention to the guidelines below. The editorial office cannot undertake preparation of manuscripts and illustrations not conforming to journal style. Manuscripts of insufficient quality will be returned immediately without refereeing. A high standard of illustration (both line and photo) is an editorial priority. All illustrations should be prepared for printing to fit 80 x 240 mm (column width) or 169 mm by up to 240 mm (full page) size. The authors should keep in mind that the full-page length is not used and the caption will be placed underneath the figure. In the event that full-page length is necessary for plates, captions will have to appear on adjacent pages. Figure(s) must be numbered consecutively in the text. Compound figures with more than one micrograph or photo should be referred by a single figure reference (e.g. Figure 1), and individual parts should be labeled with capitalized letters in the lower left-hand corner. Lettering should be of a sans-serif type (i.e. fonts without serifs such as Arial) with a minimum published size of 4.2 mm (12 pt). Descriptive labeling in the figures should be clearly readable, and all lettering should have a minimum published size of 6 pt (2.1 mm) for labeling items on photographs or in line art is recommended and a maximum size of 10 pt is suggested. Use a scale bar to indicate magnifications and place in the lower right corner if possible. Computer prepared photographic images must be at a minimum of 350 dpi at the final publication size. Lower resolution will result in pixilation and poor quality images. These should be submitted as JPEG or TIFF, but encapsulated postscript (EPS) format is also acceptable.
Computer drawn figures are accepted provided they are of high quality. Please note that graphs produced by many statistical packages are rarely adequate. In particular, letter quality on axes and captions are often poor. Such figures should be exported into an accepted graphics package and lettering rendered using a text function. Authors should note that .dot, .bmp, and .pat fills should be avoided. Do not use postscripts fill patterns as these are often based on bit map patterns that result in screening patterns during final reproduction. When filling illustrations, use fills such as lines, tints or solids. Line width minimum is 0.25 pt (0.09 mm). Also avoid the use of bitmap scans to render text and detail. Text should be saved as text at a minimum text size of 6 pt (2.1 mm). Submit line art as Corel Draw, Adobe Illustrator, or EPS files. These must be at a minimum resolution of 800 DPI at publication size. High resolution may be necessary where fine line detail is present.
For graphs, Excel graphs are also acceptable. Note that vertical axes must all be at the same scale especially when the paper compares them. Otherwise they should be produced as separate figures. Avoid 3D plots when presenting 2D data.
All tables and figures must be placed in appropriate places in the manuscript and when this is not possible, appropriate place must be indicated in the manuscript. Please note good quality figures must be submitted as separate files as said above apart from presenting a copy of the same at appropriate places in the manuscript. This will make job of the reviewer easy.
Table and Figure captions
Figure captions/legends should include a statement at the end of each caption/legend about reproduction size (e.g. at full page width, at column width). They should be single-spaced and typed in the journal format. Explanations should be brief and authors should keep in mind that captions/legends will be placed below figures.
Those who have helped the authors carry out the study and/or prepare the manuscript but have not made significant intellectual contribution to deserve authorship must be acknowledged. Mention all applicable grants and other funding that supported the work.

Non–editable graphs will not be accepted.
All text should be fully justified. Please put all primary section titles in UPPER CASE letters and subheading in both Upper and Lower Case letters. Do not number your titles (for example, 1.0 Introduction; 2.0 Background). Do not use the tab key to indent blocks of text such as paragraphs of quotes or lists because the page layout program overrides the left margin with its own, and the tabs end up in mid-sentence.
Correct / Acceptable Format
Natural products have proven to be a great source of new biologically active compounds. Thus, in an effort to discover new lead anti-malarial compounds, several research groups screen plant extracts to detect secondary metabolites with relevant biological activities that could serve as templates for the development of new drugs. Flavonoids have been isolated and characterized from many medicinal plants used in malaria-endemic areas.10 However, controversial data have been obtained regarding their antiplasmodial activity, probably because of their structural diversity. 11-13 More recently, several flavonoids have been isolated from Artemisia afra 14,16and Artemisia indica, 17-20 two plants related to Artemisia annua, the famous traditional Chinese medicinal plant from which artemisinin is isolated.
