摘　　要：采用火焰原子吸收光谱法测定了软儿梨果肉和果汁中K、Mg、Fe、Ca、Mn、Cu、Zn的含量。样品以HNO3-HCIO4消解，对消解和仪器测定条件进行了优化选择，建立了相应的原子吸收光谱测定方法。方法的RSD在1.0％～3.0％之间，加标回收率在90％～100％之间。In this paper the elements such as K、 Mg、 Fe、 Ca、 Mn、 Cu、Zn in soft pears produced in Qing hai province were determined by FAAS. The element contents in flesh and juice were compared and the elements in juice had higher content. The samples were digested with HNO3and HC104, and analyzed under the optimized FAAS conditions. The determination method was established with good precision （ RSDs of 1.0% - 3.0% ） and recoveries （90% - 100% ）.
