Presently, the demand for renewable fuel has been increasing. The trend of the word s consumption of a fossil fuel show a projected increase in future years. Eventually, these fuel will be exhausted. To counter this, biodiesel presents a viable alternative to petrochemicals fuel and derivatives because it is produced from biomass and reduces the level of emissions. This paper had as objective to extract, to characterize and to produce a biodiesel from the seed of the plant Mabea fistulifera Mart. (canudo de pito). The income s extraction of the oil seeds was about 33,5% m/m. A factorial experiment 33 was carried through to determine the best amount of catalyser, as well as the best ratio molar alcohol and oil and the ideal temperature for the biggest income of the ethyl esters produced. The results have demonstrated that the high concentrations of catalyser generated great losses of income due the soap formation. The biggest income in esters corresponded 91,96%, using molar reason 10:1 (ethanol: oil), 1.0% (m/m) of NaOH and temperature of 50° C. The most important variable for ethanolys of the oil of canudo de pito was the molar reason ethanol: oil. The temperature did not present significant effect in the income of the reaction. The quality evaluation of the biodiesel produced occurrence through of the laboratories tests such as acidity, iodine and saponification indexes; corrosivity to copper, viscosity and stability of oxidation among others based in ANP 255/2003. All the tests display excellent repeatability and the results meet of the standards specified for the regulating agencies (ANP and ASTM).
