目的：测定桃浆中微量元素的含量。方法：采用火焰原子吸收光谱法测定不同前处理方法（湿法消解法和碳化酸溶法），及不同比例HNO3+HClO4混合酸消解的桃浆中Fe、Mn、Cu的含量。结果：用不同的前处理方法得出的含量不一致，桃浆中3种金属离子含量的顺序为：Fe>Mn>Cu，且回收率在92.6%~119.6%间，RSD<2.86%。结论：该方法准确度高，稳定性好，结果准确可靠，同时证明桃浆中含有丰富的Fe、Cu、Mn，为进一步研究桃浆药理作用提供参考依据。
目的：測定桃漿中微量元素的含量。方法：採用火燄原子吸收光譜法測定不同前處理方法（濕法消解法和碳化痠溶法），及不同比例HNO3+HClO4混閤痠消解的桃漿中Fe、Mn、Cu的含量。結果：用不同的前處理方法得齣的含量不一緻，桃漿中3種金屬離子含量的順序為：Fe>Mn>Cu，且迴收率在92.6%~119.6%間，RSD<2.86%。結論：該方法準確度高，穩定性好，結果準確可靠，同時證明桃漿中含有豐富的Fe、Cu、Mn，為進一步研究桃漿藥理作用提供參攷依據。

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 .
