Journal Scope

The Tropical Journal of Natural Product Research is open access, peer-reviewed international journal aimed at making important contributions in the field of Natural Product Research, Pharmaceutical and Natural Sciences. The journal covers all aspects of Pharmaceutical research, chemistry and biochemistry of naturally occurring compounds, ethnomedicine, ethnopharmacology, pharmacognosy, biomedical research, biotechnology and related disciplines. The journal welcome submissions from a broad spectrum of scientific endeavour involving biological evaluation of natural substances of plant, microbial and animal origin against different disease targets, processes or therapeutic strategies that can lead to or assist in the prevention and management of chronic and infectious diseases, clinical therapeutics, Isolation and characterization of metabolites, structure elucidation, synthesis and experimental biosynthesis of natural Product as well as developments of methods in these areas. Research papers in the fields of chemistry-biology boundary, e.g. fermentation chemistry, plant tissue culture investigations etc. are also welcomed. Although the journal focuses mainly on original research articles, timely, concise and focused reviews on recent progress in active areas of natural Product is also encouraged.

Manuscript style and format

Articles should be original research work written in English in a concise and understandable manner. It is advised that authors who may want professional assistance with improving the English, or formatting in their manuscript should do so before submitting their manuscript. Manuscript should be in MS word, double-spaced on A4 (8.5" x 11") paper size with 1 inch margins. Article should be in the order:

  1. Title
  2. Abstract
  3. Keywords
  4. Introduction
  5. Materials and Methods
  6. Results and Discussion
  7. Conclusion
  8. Conflict of Interest
  9. Acknowledgement
  10. References

Title Page

The title should be concise and reflect the key elements of the research. The title should be followed by authors’ full name and affiliations. The corresponding author should be indicated with an asterisk and provide the full corresponding address (e-mail address and telephone number).

Abstract

Abstract should start on a new page after the title page. Abstract should briefly state the purpose of the research, methodology, principal results, main findings, major conclusions and should not be more than 250 words. Abstracts should not be referenced and the use of abbreviations should be minimized and spelled out when first used.

Keywords

Abstract should be followed by 4-6 keywords, provided by the authors and separated by a 'coma'.

Introduction

A referenced introduction should set the work in context. The introduction should be kept to a minimum length and relevant to the research described. It should state the rationale, justifications and objectives of the research. Detailed descriptions of routine experimental procedures should be avoided.

Materials and Methods

Authors should provide sufficient experimental details to allow others to reproduce the findings presented, but where necessary, synthetic and bioassay protocols should refer to published procedures by literature citation of the original method and any later modifications used. Spectroscopic data for characterization of new compounds should be described in sufficient detail. Plants must be properly identified and authenticated by a taxonomist or experienced botanist and specimen must be deposited in recognized herbarium and voucher number must be stated. Where possible, supporting Information can be useful for presenting experimental details while limiting the size of the main document. This should be divided into subsections if several methods are described.

Ethical consideration on use of experimental animals and human subjects

Experiments involving the use of live animals must include a statement of approval by an ethical committee and certifying that such experiments were performed in accordance with all international guidelines and regulations. For experiments involving humans or tissue samples, a statement that informed consent was obtained from the subject or from the next of kin must be included.

Results and Discussion

The Results and Discussion may be combined into a single section or presented separately. They may also be broken into subsections with short, informative headings. Authors should present their data in a clear and interpretative manner. Presentation of data should not be duplicated. Discussion should interpret the results and relate them to existing knowledge in the field (with relevant literature). Supporting information can be used if this help to make the result clearer. All results presented in tabular form or graphical form should be comprehensively described in this section.

Presentation of NMR Data

Coupling constants for protons in a 1H NMR: Always give coupling constants for well resolved peaks. After each chemical shift, enter in parenthesis number of protons, multiplicity, coupling constants, and assignment in that order.

Chemical shift of 13C NMR: Carbon-13 NMR data should be reported to the nearest 0.1 ppm with the number of attached hydrogens designated as CH3, CH2, CH and C group.

Authors are also advised to present NMR data in tabular form. The title of the table should accurately and concisely reflect the contents of the table.

Conclusion

Authors should state their conclusions or the significance of their findings following the discussion of results. Conclusions should also be summarized in the abstract in order to place the authors’ research in proper perspective.

List of abbreviations

If abbreviations are used in the text, they should be defined in the text where first used.

Tables and Figures/Graphics

Tables and figures showing the results of the experiment should be placed at the end of the manuscript after the list of references. Tables and figures not displaying the results of the experiment should be placed within the body of the manuscript closed to the point where they are mentioned. All tables and figures should be referred to in the text of the manuscript.

Tables

Tables should have the following characteristics:

  • The table should be created using table format feature. Ensure each data entry is in its own table cell.
  • Tables should be without borders and shadings except for column headings and bottom border.
  • Tables should be consecutively numbered using Arabic numerals.
  • Tables should have a descriptive heading that, together with the individual column headings, makes the table self-explanatory.
  • Footnotes should be given letter designations and cited in the table by superscript letters.

Figures/Graphics

Figures/graphics should give the reader a quick visual representation of the important results and/or the essence of the paper without providing specific details. All figures/graphics should be submitted using the following guidelines:

  • Embedded figure or graphic files in a Word document is preferred.
  • The following file format is also accepted; TIFF, PDF, EPS (vector artwork) or CDX (ChemDraw file).
  • Chemical structures should be drawn using ChemDraw and formatted per the American Chemical Society (ACS) document settings.
  • Graphics with similar information should be of similar size.
  • All figure parts should be labeled and grouped into a single graphic.
  • Figure/graphic should be clear, simple, relatively free of text and technical characters, and make use of color for visual impact.
  • Graphic files should be consecutively numbered using Arabic numerals and should have a descriptive title and named based on graphic function (i.e. Scheme 1, Figure 2, Chart 3).

Conflict-of-Interest Disclosure

A statement describing any financial conflicts of interest or lack thereof is published with each manuscript. During the submission process, the corresponding author must provide this statement on behalf of all authors of the manuscript.

Acknowledgements:

Funding body and all those who assisted in the work but may not qualify as an author should be acknowledged.

References:

References should follow the Vancouver citing and referencing style;

  • The in-text citation is indicated by a number (use Arabic numerals).
