Abstract We have determined the concentrations of eight REE elements by instrumental neutron activation analysis (INAA) (La, Ce, Nd, Sm, Eu, Tb, Yb, and Lu) in plant leaves of the species Solanum lycocarpum, a typical Brazilian "cerrado" plant widely distributed around the country, and in the soils in which they grow. Three different ecosystems were studied. Very similar chondrite normalized patterns were observed in the soil and in the plant, presenting an enrichment of the light REE, indicating a typical absorption of these elements by this species.
