Abstract. The chemical composition of the leaves of Pistacia vera has been studied for the first time. Plant material was successively extracted with chloroform and 70% acetone. The acetone extract was distilled off on a rotary evaporator to an aqueous residue. The aqueous portion was then fractionated with ethyl acetate. Individual compounds were separated by column chromatography and their chemical structure was established by physicochemical (UV, IR, NMR, mass spectroscopy) research methods
