Aim and editorial policy

The Revista Brasileira de Farmacognosia (Brazilian Journal of Pharmacognosy) is a periodical dedicated to the publication of original scientific work, reviews and divulgation in the field of Pharmacognosy (the study of biologically active natural products).

Original Articles (in Portuguese, English or Spanish): it refers to unpublished research works. They must follow the usual presentation form, containing Introduction, Material and Methods, Results and Discussion, etc, according to the peculiarities of each work.

Review Articles (in Portuguese, English or Spanish): they are directed to the presentation of the progress in a specific area of Pharmacognosy, containing a critical view, with the main objective of benefiting the group formed by post graduating students and non-specialists in the area. The RBFAR Editors can, fortuitously, invite qualified researchers to submit review article. It is desirable that the author has publications in the refereed area.

Divulgation Articles (in Portuguese, English or Spanish): presentation of some aspect or area of Pharmacognosy, written down in a didactic way, with the objective of benefiting the group formed by graduating and post graduating students, non-specialists in the area, pharmacists and professors of alike areas.


Form and preparation of manuscripts


1.1 All submitted manuscripts should be unpublished. The simultaneous submission of manuscripts describing the same work to other journals is not acceptable. The rights of publication are reserved, including translations; subsequent publication is allowed with the citation of the source.

1.2 The Revista Brasileira de Farmacognosia receives for publication original scientific work, reviews and divulgation articles written only in English. The content of the text is the entire responsibility of the author(s), and does not necessarily reflect the opinion of the Editor, Section Editors or the members of the Editorial Board.

1.3 Language of publication is English. Manuscripts written by authors whose mother language is not English should be checked by a native speaker or a professional language editing service before submission to improve the English. Assistance of independent editing services can be found at All services are paid for and arranged by the author, and use of one of these services does not guarantee acceptance or preference for publication.

1.4 The Revista Brasileira de Farmacognosia reserves the right to submit all received manuscripts to ad hoc referees, whose names will be kept confidential and who will have the authority to decide on the pertinence for acceptance. Referees may send back manuscripts to Editor-in-Chief for transmission to the author(s) with suggestions for necessary alterations to the manuscripts which are to be made in order to conform to the standards and editorial rules of the Journal.

1.5 Every idea and conclusion presented in a published paper are the exclusive responsibility of the author(s), and do not necessarily reflect the opinion of the Editor, Section Editors or the members of the Editorial Board.

1.6 Every article involving studies with humans or animals should have the approval of the Ethics Committees on Research on Human Beings or on Animals of the institutions to which the author(s) belong, authorizing such studies.

1.7 All plant materials used in the described research should be supported by an indication of the site (including GPS coordinates, if possible) and country of origin, the name of the person identifying the plant material and the location of the voucher specimen. Authors should be prepared to provide documentary evidence that approval for collection was afforded from an appropriate authority in the country of collection.

1.8 The following immediate rejection criteria apply: i) the manuscript does not fall into of the areas of interest of the Journal; ii) the manuscript is too preliminary, reporting activity data without comparison to a reference, or without a positive control; iii) the botanical source is not clearly identified, authenticated, and documented; iv) experimental studies of antimicrobial and antioxidant activity with crude extract, without isolation and identification of active compounds.


2.1 The author(s) should retain a copy (electronic and paper) of the submitted manuscript, in the event the loss or damage to the original sent to the journal.

2.2 The figures (photographs, charts, drawings etc.) should be presented after the References and numbered consecutively in Arabic numbers. The respective captions should be clear, concise, without abbreviations, and be located underneath the figures. Their respective position in the text should be indicated preferentially just after their citation in the body of the manuscript.

2.3 Tables and charts should be presented after the References and numbered consecutively using Arabic numbers. The tables (numeric data) should not be closed by side lines. The respective captions should be clear, concise, without abbreviations and located above the table. There should be an indication of the approximate position in the text where tables or charts should be placed, preferentially, just after their citation in the body of the manuscript.

2.4 The captions of botanical illustrations should be in accordance with the rules adopted by the Journal. Request the standards to


3.1 Original Papers. Original papers are research articles describing original experimental results. The manuscript should be arranged in the order: Title, Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion, Acknowledgements, References, Figure with Legends, Tables, Structural Formulas. Results and Discussion sections may appear as two separate parts or as a combined "Results and Discussion" section. The normal length of the main text of an Original Paper, excluding references, tables, figures and figure legends, is about 3,000 words. In exceptional and well justified cases longer manuscripts may be accepted. When submitting such manuscripts, authors should provide a justification statement, giving compelling reasons for the length of the paper.

3.2 Short communication: This section will cover mainly the isolation of known compounds from new neotropical fonts, or complementary results of an ongoing work. The communication should be arranged in the order: Title, Abstract of 200 words, Keywords, Introductory Remarks, Materials and Methods with brief experimental details without subheadings, Results and Discussion as one body of text without headlines, Acknowledgements, References up to 20 citations, Figure and/or Tables up to 3. Authors should limit the text, which should not exceed 2,000 words.

3.3 Reviews will generally be invited by the Editor-in-Chief. They should be as concise as possible and do not need to include experimental details. The main purpose of reviews is to provide a concise, accurate introduction to the subject matter and inform the reader critically of the latest developments in this area.

3.4. In addition to the Guidelines, a template (for original papers) and a sample letter are available at Authors are urged to follow these formats when preparing a manuscript.

3.5 The originals should be printed on A4 size paper, double spaced using Times New Roman font, font size 12, fully justified, and with margins of 2 cm. They should have a maximum of fifteen and a minimum of five pages including figures, tables and charts.

3.6 Title and subtitle: They should be in accordance with the contents of the article, taking in consideration the scope and objectives of the Journal. They should be in lower case, using Times New Roman size 14 font. Plant name should be complete including author name and Family according to

3.7 Authors: The authors' names should appear underneath the title, centered. The first and last name should appear complete, followed by the initials of all other names (e.g. Carlos N. U. Silva or Carlos N. Ubiratan Silva). In the case of several authors, their names should be separated by commas.

3.8 Authors' affiliation: After each author name there should be superscript Arabic numbers indicating the institution to which they are affiliated. The list of institutions should appear immediately below the list of authors. The name of the main author should be identified with a superscript asterisk indicating the address to which all correspondence should be sent. The electronic institutional address and telephone of the main author should appear as a footnote at the first page. The Journal will not publish commercial e-mail address.

3.9 Abstract: A brief and concise abstract (maximum 200 words) of the article, in either the Portuguese and English language, highlighting the more important information, the methodology, the results, and the conclusions. This will allow the reader to evaluate their interest in the article and thus avoid having to read the full work. For authors outside Brazil, the abstract in Portuguese will be done by the journal.

3.10 Keywords: The authors should identify a maximum of six Keywords to represent the content of the article. Keywords are very important for data base searches, thus validating the article. The keywords should be separated by commas.

3.11 Introduction: The Introduction should clearly establish the objective of the work and its relationship with other works in the same field. Extensive literature reviews should be replaced by references to more recent publications, where these reviews have been published and are available.

3.12 Material and methods: The description of the material and the methods used should be brief, but sufficiently clear to make possible the comprehension and the reproducibility of the work. Processes and techniques already published, unless extensively modified, should be referenced.

3.13 Results: The Results should be presented with a minimum personal discussion or interpretation, and whenever possible, be accompanied by adequate tables and figures. The data, when pertinent, should be submitted to statistical analysis.

3.14 Discussion: The Discussion must be restricted to the significance of the obtained data and the achieved results, avoiding conclusions not based on them. Alternatively, at the discretion of the author, the Results and Discussion could be presented in one section.

3.15 Acknowledgements: This is an optional item and should appear before the references.
