Categories of Manuscripts
Review Articles (by invitation only)
Reviews provide a comprehensive summary of broadly-based topics of general interest to natural product research scientists. Reviews are not limited as to the number of words, tables, figures and references that may be included. Unsolicited reviews are considered only if they are authored by investigators who have demonstrated expertise in the relevant areas. An author interested in preparing a Review for Tropical Journal of TJNPR should provide the title, abstract and a brief outline to the Editor-in-chief, Prof. Falodun requesting an invitation to submit a manuscript in this category.
Manuscript in this category discusses important parts, overlooked aspects, or lacking parts of a previously published article. Articles on subjects within the scope of the journal that might attract the readers’ attention, may also be submitted in the form of a “Editorial Note.” Readers can also present their comments on the published manuscripts in the form of a “Editorial Note”. Abstract, Keywords, and Tables, Figures, Images, and other media should not be included. The text should be unstructured. The article that is being commented on, must be properly cited within this manuscript.
Research Articles are comprehensive accounts of significant and original experimental and/or theoretical results that fit within the scope of Tropical Journal of Natural Product Research (TJNPR). They contain innovative, original, hypothesis-driven research that is supported by sound experimental design, methodology, and data interpretation. TJNPR publishes research articles in the multidisciplinary field of pharmaceutical sciences. Authors are asked to write their manuscripts in a clear, concise and excellent manner.
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.

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).
Ingredients of title
- Titles are of great importance for current awareness and for information retrieval.
- Avoid abbreviations and formulae, where possible.
- The wording of titles should be chosen carefully to provide information on the contents and to function as "points of entry" for information retrieval. Symbols, formulas, or arbitrary abbreviations should not be included in the title, except chemical symbols to indicate the structure of isotopically labelled compounds. Full title must be in sentence case.
- The title of the manuscript must be written in lower case except for the first word and proper nouns.

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.
Abstract should be followed by 4-10 keywords, provided by the authors and separated by a 'coma'. The keywords should be listed in full without abbreviations.
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. The introduction must be designed to inform the reader of the rationale and significance of the study.
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.
Ethical consideration on use of experimental animals and human subjects

All tables and figures should be referred to in the text of the manuscript.
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.
