Jatropha dioica Seseé is a species of the Euphorbiaceae family, it belongs to the group of endemic species in Mexico that have not been studied and valued as a phytogenetic resource. Its seeds are rich in oil and its stems contain pharmacological and healing properties. The objective of this work was to evaluate the potential of Jatropha dioica Seseé seed oil as a raw material in the production of biodiesel. Seeds of Jatropha dioica Seseé were subjected to extraction, by means of Soxhlet and maceration methods. The obtained oil was physico-chemically characterized and a reaction was made with methanol, in the presence of potassium hydroxide as a catalyzer to obtain a mixture of fatty acids methyl esters (FAME), which was analyzed to evaluate its possible use as a biodiesel. The exhaustive extraction of Jatropha dioica Seseé seeds provided 55.8 % of oil by Soxhlet method, while 43.5 % of oil was extracted by maceration method. Crude oil acid (0.63 ± 0.03 mg KOH g-1) and saponification indexes (44.48 ± 1.27 mg KOH g-1) were considered to carry out biodiesel production by means of alkaline trans-esterification reaction. The analysis of FAME revealed the presence of a high content of linoleic acid (57.77 %) and oleic acid (23.86 %). According to the obtained results, the extraction of Jatropha dioica Seseé seed oil was recommended for its possible use as a biodiesel in the energy industry.
