【 摘 要 】

The trees from the Burseraceae family exude a resin widely used for both cosmetics and perfumes and in folk medicine, for the treatment of many diseases. Samples of oleoresin from five species (Protium cf. apiculatum, P. cf. hebetatum, P. cf. heptaphyllum, P. tenuifolium and Trattinnikia peruviana) were collected in the Reserva Biológica Adolfo Ducke (Manaus-AM, Brazil) and analyzed through EDXRF for determination and quantification of the chemical elements with atomic numbers from 11 to 92. In all samples the elements S, Cl, Ca, Fe, Ti, V and Si, were observed the last one having the highest concentrations (13.1%, m/m). In addition to these elements, Na, P, Al, Mg, K, Cr and Mn were also detected. Except for sulfur and aluminum, the variation of concentration of the elements present in the sample was very small (CV < 13%, m/m), suggesting a pattern of inorganic composition for the resins of this region. Some elements were detected in just some species, suggesting different capacities of absorption.
