The Brazilian Amazon forest has a very rich diversity of plants and fruits. And from these plants and fruits, natural oils are produced. These natural oils are sold in local markets in northern Brazil for various purposes. The most commercialized natural oils are copaiba (Copaifera l.), andiroba (Carapa g.), buriti (Mauritia f.) and tucumã (Astrocaryum v.). This research aimed to analyze the thermal degradation by TGA and perform the FTIR analysis of these natural oils. It was possible to verify, in a comparative way, which of the four oils showed the greatest mass loss. The oil that had the highest degradation temperature was also observed. In addition, this work also presents the Tonsets of each oil. According to the FTIR analysis of the oils, the presence of functional groups in organic samples was noted, such as hydroxyls, carboxyls and epoxies. The data obtained corroborate the data found in the literature.
