Abstract: This study was aimed to determine trace elements in Peach pulp . The wet digestion method and car-bonize acid dissolution method were applied to digest the sample, and flame atomic absorption spectroscopy was used to determine the content of trace elements (Fe, Cu, Mn) in Peach pulp . The results showed that the content is not consistent among different pretreatment methods. However, the metalion content among these three methods are in the order of Fe > Mn > Cu, with the average recovery rate between 92.6% and 119.6%. The RSD is less than 2.86%. It was concluded that this method is with high accuracy and stability as well as reliable accurate re-sults. It also proved that Peach pulp . is rich in Fe, Cu and Mn. It provides some useful information for further pharmacological study of Peach pulp .
