摘要： RationaleThe identification and quantification of phytochelatins (PCs) and their derivatives are important to understand their roles in plant growth and development. A method couplling high-performance liquid chromatography with hybrid linear ion trap Orbitrap mass spectrometry (HPLC-LTQ/Orbitrap) was developed to screen PCs that have the same characteristic product ions. This approach was used for the fragmentation pattern analysis of glutathione (GSH) and PC standards, which allowed identification of the fragmentation pathways of their derivatives isolated from rice roots, stems and leaves.
