Categories of Manuscripts

Review Articles (by invitation only)

Reviews provide a comprehensive summary of broadly-based topics of general interest to pharmaceutical and 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 Phytochemistry and Pharmaceutical Sciences 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.

The text should be unstructured. The article that is being commented on, must be properly cited within this manuscript.

Research Papers

Research Articles are comprehensive accounts of significant and original experimental and/or theoretical results that fit within the scope of TJPPS. They contain innovative, original, hypothesis-driven research that is supported by sound experimental design, methodology, and data interpretation. Tropical Journal of Phytochemistry and Pharmaceutical Sciences publishes research articles in the multidisciplinary field of pharmaceutical sciences. Authors are asked to write their manuscripts in a clear, concise and excellent manner.
