Abstract：Today researchers pay more and more attention to the content of trace elements and heavy metals in food.Contents of trace elements and heavy metals in Chinese winter jujube fruit were analyzed by ICP-MS，the results showed that winter Chinese jujube contained plentiful trace elements, especially Ca(126.67 μg·g-1·FW), Mg(68.04 μg·g-1·FW), Sr(1 691.39 ng·g-1·FW), Zn(787.26 ng·g-1·FW), Fe(512.84 ng·g-1·FW), Mn(495.42 ng·g-1·FW) and Mo(33.38 ng·g-1·FW), which is necessary for human health and can prolong the human life.But Chinese winter jujube contains little heavy metals and accords with relative national standard.
