摘要：Date fruit contains a wide range of metals,including essential and toxic elements. The aim of present study was to explore the amount of essential metals in branch,pericarp and seed of the date fruit in order to examine correlation of these metals at various maturity stages. The studied parts are generally considered as waste. Therefore,levels of essential elements such as Na,Mg,Ca,Fe,Mn and Zn were determined in the branch,pericarp and seed of three date varieties ( Dallay wari,Noori and Khaki wari) at four ripening stages (kimri,khalal,rutab and tamar) using atomic absorption spectrophotometry. Oven dried samples were digested separately in HNO3 and H2O2 following wet acid digestion method. Analytical results show that Na,Mg,Fe,Zn,and Mn were not detected in branch,pericarp and seed in Dallay wari variety at tamar stage,while Na and Mn were also absent in branch of Noori at tamar stage,whereas Mn was present in pericarp and seed at tamar stage of Noori variety. However,Mg was not detected in branch and pericarp at rutab and tamar,while Fe was not detected in pericarp at rutab and tamar stage in Khaki wari vareity..
