The aim of the study was to determine contents of macro- and microelements in extracts from yellow and green leaves of Ginkgo biloba. The following elements: Mg, Cu, Zn, Cr, Fe and Se were determined by atomic absorption spectrophotometry. The concentrations of these elements varied depending on the vegetation period of leaves and the extraction solvent. The highest concentration of Mg was observed in water extract. The highest levels of iron and the other microelements were observed in water extracts from green and yellow leaves.
