Abstract: Jujube leaf tea, which is made from the young leaves ofZiziphus jujuba, is a novel functional herb tea or infusion that inhibits the central nervous system. In the current study, the effects of iminodisuccinic acid (IDS), as a metal complexing agent, on mineral element content, oxidative damage, antioxidant enzyme activities, and antioxidant accumulation in the young and mature leaves ofZ. jujubawere investigated. Results demonstrated that foliar fertilization with ionic (FeCl2and ZnCl2) and chelated (Fe-IDS and Zn-IDS) fertilizers could drastically enhance iron and zinc contents, coupled with increased vitamin C level, glutathione accumulation, total phenolic content, and total antioxidant capacity (evaluated based on the Fe3+reducing power of leaf extracts), compared with the control, particularly in young leaves. However, chelated fertilizers considerably reduced the chlorophyll level, H2O2content, and lipid peroxidation rate than ionic fertilizers, particularly in young leaves. Compared with the control, chelated fertilizers induced greater superoxide dismutase and catalase activities, particularly in young leaves. Moreover, decreased enzyme activities were observed in the ionic fertilizer-treated leaves compared with the control-treated leaves. Thus, using a chelating agent could improve the accumulation of mineral elements and antioxidants in young leaves by reducing metal-mediated reactive oxygen species toxicity.
