The oxidative processes occur due to high temperatures and the presence of unsaturated fatty acids, making a challenge to keep the quality of the biodiesel produced. In this sense, this paper presents data about the antioxidant influence of biodiesel obtained from the Moringa oleifera Lam mixed in different percentages with soybean biodiesel, the most used oil for biodiesel production in Brazil (81%). The samples were characterized about oxidative stability by the Rancimat method, Concentrations of 100, 500, 1000, 2000, 3000, 4000 and 5000 ppm. All samples were analyzed at time zero. The results obtained showed that the oxidative stability time exceeded the limit established by ANP (minimum 8 h) only from the concentration of 2000 ppm, and revealed that the higher antioxidant concentration used, the greater the oxidative stability.
