Therefore, authors are strongly encouraged to read these instructions carefully before preparing/submitting their manuscript for publication. A statement by the corresponding author confirming that the manuscript has not been submitted to any other journal for publication is required in the forwarding letter for submission of an article.
Authors should note that submission of a manuscript to TNPR journal for publication implies that the same work has not been previously published nor under consideration for publication elsewhere. Authors, in their cover note to the editor, have to clearly state whether the manuscript shall be considered as a Research Paper, Case Report, Short Communication or as Letter to the editor. Review Articles within the stipulated scope of the journal is also acceptable for publication.
Authors publishing results from in vivo experiments involving animals or humans should clearly indicate, by including a statement to this effect, in the Materials and Methods section, whether due permission for the conduct of such experiments was obtained, from the relevant institutional ethics committee.
Full length research articles
Manuscript should be submitted online at journal website (www.tnpr-napreg.com) or sent by email to: firstname.lastname@example.org Electronic submission should also include a covering letter. The covering letter should include a certificate that “The submission has not been previously published nor is it before another journal for consideration; or an explanation has been provided in Comments to the Editor”.
Language of publication is only English. British English spelling and punctuation is preferred.
All submitted papers are reviewed by invited reviewer(s), the Editor-in-chief or members of editorial board. Reviewer’s comments and/or reviewed MS will be sent to corresponding author as email attachment for response and/or correction. Final decision regarding publication of paper will be made by the Editor-in-chief as soon as possible.
The preferred format of all manuscripts is MS Word. Figures, images (in JPEG, TIFF or SFC format), illustrations and tables should be inserted in the manuscript immediately they are mentioned. Manuscripts must be typed, double-spaced on A4 (8.5″ × 11″) paper size with 1 inch margins and should be arranged in the following order: Title, Abstract, Keywords, Introduction, Experimental (or Materials and Methods), Results, Discussion (or Results and Discussion), Conclusion, Acknowledgement (if any), References.

The abstract should be non-structured and should start on a new page after the title page and should present the reason for the study, the methodology, the main findings, and principal conclusions and should not be more than 300 words. All the three categories, Review Articles, Research papers and Short Communications should have an Abstract.
Keywords (3-6) are to be provided by the authors separated by a ‘coma”.
The introduction section should represent the scope, objective and novelty of the research work. This should start on a new page and should clearly indicate the objective(s) of the study. It should provide an adequate background, avoiding a detailed literature survey or a summary of the results.
Materials and Methods
This section should contain information about the materials and the methods adopted to carry out the research work like animals, chemicals and animal ethical committee permission, software used, and procedures followed etc. Chemical compounds should be named according to IUPAC or Chemical Abstracts. The units and dimensions should be expressed according to the metric system and SI units. It should include concise details on the methodology adopted, enough to repeat the experiment. Extracts and/or fractions tested for in-vitro or in vivo biological activities should be chemically defined, at least by means of the results of preliminary phytochemical screening. Complete formulation details of all crude drug mixtures and extracts should be mentioned. The plant name should be fully mentioned when cited first, and the authors are asked to add the details regarding its identification, voucher herbarium specimen number and name of the herbarium institution where it has been deposited.
Abbreviations should be preceded by words for which they stand at the first appearance in the manuscript. The statistical method and the level of significance chosen should be clearly stated.
All results presented in tabular or graphical form shall be described in this section. Figures (photographs, drawings, diagrams and charts) should be clear, easily legible and cited consecutively using Arabic numerals in the text (Figure 1, Figure 2…etc.). Legends should contain sufficient detail to permit figure interpretation without reference to the text. Tables must be concise and cited consecutively using Arabic numerals in the text (Table 1, Table 2…etc.). Each table should be typed on a separate sheet. The title of the table should clearly indicate the nature of the contents and enough detail should be included in the footnote to facilitate interpretation without reference to the text. Use horizontal rules only. All Tables and figures must have a title and a legend to make them self-explanatory and they should be numbered. Identify statistical significance using superscripts (* and **) following the data (*P < 0.05, **P < 0.01).
Discussion and Conclusion
Discussion and conclusions should contain a critical review of the results of the study with the support of relevant literature. It can end with brief conclusions.
It should contain the information regarding any research grant support or the assistance of colleagues.
Conflict of Interest:
Authors should dedicate a section to report any possible conflict of interest in the execution and reporting of the studies. Where no conflict of interest exists, authors should state so explicitly in the section.
References should be organised in alphabetical order. All papers cited in the text should be given in parentheses using the (author surname, year) format and in chronological order e.g. (Nworu et al, 2008; Akah et al., 2010) except when the authors are mentioned, e.g., “….according to the study of Nworu and Akah (2015)”. Use complete name of the journal for non-indexed journals. Information from manuscripts submitted but not accepted should be cited in the text as “unpublished works” with written permission from the source. Avoid citing a “personal communication” unless it provides essential information not available from apublic source, in which case the name of the person and date of communication should be cited in parentheses in the text.
The complete reference list should be provided at the end of the text according to the format and examples as shown hereunder:
