In this study ,HPLC-MS and ICP-MS methods wereused for the determination of histidine and cad-miuminEleagnusangustifoliaL.,VitisviniferaL.andNeriumoleanderL.leavestakenfromindustrialarea including Gaziantep and Bursa cities .To histidine determination by HPLC-MS ,flow rate of mobile phase , fragmentor potential ,injection volume and column temperature were optimized as 0.2 mL · min-1 ,70 V ,15μL and 20 ℃ ,respectively .For extraction of histidine from plants ,distilled water was used by applying on 90℃ and 30 min .The concentrations (as mg · kg -1 ) of histidine were found to be in range of 8~22 for Eleag-nusangustifolia L .,10~33 for Vitisvinifera L .and 6~11 for Nerium oleander L .The concentrations of cadmium were found to be in ranges of 6~21 μg · kg -1 for Vitisvinifera L .15~110 μg · kg -1 for Eleagnu-sangusti f olia L .and 63~218 μg · kg -1 for Nerium oleander L .
