The objective of this study was to determine the level of selected metals in the leaves of Ruta chalepensis L. (Rue) cultivated in Ethiopia. Rue leaves samples were randomly collected from four different parts of Ethiopia (Kality and Alem Bank from Addis Ababa Administration, Holeta (Oromia Region) and Worabe (South Nations and Nationalities Peoples Region)). A 0.5 g Rue sample was digested with 3.0 mL of 69.5% HNO 3 and 1.0 mL 70% HClO 4 and the levels of selected metals were determined by flame atomic absorption spectrometry. The validity of the optimized procedure was evaluated by analyzing the digest of the spiked samples with standard solution and the percentage recoveries varied from 92.0 to 102%. The levels of metals determined in mg/kg dry weight were in the ranges Ca (1872–3077), Zn (44.5–64.0), Cu (
