title: Examination of Correlation between Histidine and Cadmium Absorption by Eleagnus angustifolia L., Vitis vinifera L. and Nerium oleander L. Using HPLC-MS and ICP-MS.
abstract: In this study, HPLC-MS and ICP-MS methods wereused for the determination of histidine and cadmium in Eleagnus angustifolia L., Vitis vinifera L. and Nerium oleander L. leaves taken from industrial area 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, 15 µL and 20 °C, respectively. For extraction of histidine from plants, distilled water was used by applying on 90 °C and 30 min. The concentrations (as mg · kg⁻¹) of histidine were found to be in range of 8~22 for Eleagnus angustifolia L., 10~33 for Vitis vinifera 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 Vitis vinifera L. 15~110 µg · kg⁻¹ for Eleagnus angustifolia L. and 63~218 µg · kg⁻¹ for Nerium oleander L.
