Abstract
The composition of seed oil of three endemic Mexican species of Jatropha is described. Oils were analyzed through the formation of their corresponding methyl esters and their yield and composition were found to be close to that of the oil of Jatropha curcas L. The results show that the three species studied are potential sources of biofuels and therefore are promising alternative crops for biodiesel production in the arid regions of Mexico.
Keywords: Fatty Acids, Plant oils, seeds, Jatropha species.
Resumen
Se describe la composición de los aceites de semillas de tres especies de Jatropha endémicas de México. Los aceites fueron analizados a través de la formación de los ésteres metílicos y se encontró que sus rendimientos y composición guardan similitud al aceite de Jatropha curcas L. Los resultados muestran que las tres especies analizadas son fuentes potenciales para la producción de biocombustibles y por lo tanto son cultivos alternativos promisorios para la producción de biodiesel en las regiones áridas de México.
Palabras clave: Ácidos grasos, aceites vegetales, semillas, especies de Jatropha.
