The time frame for the information retrieval covers the last twenty years, from 2010 (WoS) and from 2005 (Scopus) to 2023 in both cases. The search using bibliometric equations yielded 95 documents in WoS and 237 in Scopus. After filtering these documents based on the search criteria (see section 2.2.1), the numbers were reduced to 23 for WoS and 40 for Scopus. The relatively small number of results after filtering can be attributed to the specific focus of the study. We concentrated on research relevant to NPs derived from plants specific to the coffee region of Colombia. This targeted approach ensures that only the most pertinent publications are included in the analysis, providing a more accurate and meaningful overview of the current state of research in this particular field. Additionally, the inclusion criteria were necessary to maintain the relevance and reliability of the data. The number of results also indicates the visibility of research on this topic and for this region of the world in these two databases.
