The Andiroba belongs to the botanical family Meliaceae, found in the Amazon mainly two varieties, Carapa guianensis and C. procera. They are species with large logging utility and extracted oil has many uses, especially in lighting, such as healing use, insecticide and anti-inflammatory. In this paper the physico-chemical properties of oil of C. guianensis in São João da Beacon, Roraima through calculations from 1H NMR spectrum using the computer program PROTÓLEOS properties are studied by ESI-MS technique to determine the constituents of said oil are linolenic acid (9.99%), linoleic acid (13.14%), oleic acid (47.32%), unsaturated (70.45%) fatty acid and saturated fatty acids (29.55%). The extracted oil of andiroba oil has a yield of 67.03% being the physicochemical properties of the oil as follows: 48.4 mg I2 / g of iodine; 161.67 mg KOH / g of saponification; 1.84% of acid; 1004.02 g / mol average molecular weight; 159.83 mg KOH / g of ester value; 98.87% percent of ester and 0.9166 g / cm3 for the density at 25 ° C. Constituents determined by ESI-MS include: 1,1'-methyl-2,2'-dicarboxylate diantraquinona, dimethyl pirofosfatosantoninate, 2,4,6-tris- (3,5-di-butyl-4-tec -hidroxibencil) styrene, (2,3,7,8,12,13,17,18-octanoilporfirinate) -Mg (II).
