Resumo
Jatropha curcas L., popularly known as the physic nut, is a monoecious, perennial lactiferous species
belonging to the family Euphorbiaceae. Recently, interest in this species has been growing, due to its
ability to flourish on degraded land and in soils with low natural fertility, the high oil content of its seeds,
its rapid growth and easy propagation, and the identification of several secondary metabolites with
medicinal importance. This study aims to report the main trends and gaps in the global scientific literature
about J. curcas L, using a scientometric analysis. We have carried out this scientometric analysis on
the global literature to identify: 1) temporal publication trends; 2) the quality of scientific production,
estimated using citation numbers and journal impact factors; 3) the main journals and countries interested
in this topic and the language of scientific divulgation; 4) the main research fields; 5) the use of wild
or commercial cultivars; and 6) average authorship levels and international collaboration networks.
Our findings have revealed a continuous increase in both quantitative and qualitative parameters in
studies about J. curcas. The main trends in physic nut studies involve biofuel production and the plant’s
agronomic characteristics. The main knowledge gaps relating to J. curcas are in the fields of forestry,
sustainability, animal nutrition, and genetic improvement. Another problem identified in this study is a
lack of commercial seeds; none of the studies analyzed have used commercial seeds. India, Brazil, and
China together are responsible for 55% of the knowledge about this species, obtained through scientific
production. Only moderate international collaboration has been observed between countries, perhaps
as consequence of conflicts of interest. Despite an increasing number of articles, some countries have
stopped producing J. curcas L, and the worldwide crop production has decreased.
