摘　　要：目的：测定松花粉中矿物质元素的含量并进行分析。方法采用微波消解方法对松花粉样品进行前处理，原子吸收光谱法测定松花粉中K、Na、Ca、Mg、Fe、Cu、Zn、Mn 8种元素含量，并进行加标回收率和精密度试验。结果样品测定结果的相对标准偏差为0．018％～1．781％，各元素的加标回收率为90．0％～101．1％之间。结论松花粉中含有丰富的对人体有益的矿物质元素，且含量顺序为K＞Mg＞Na＞Ca＞Mn＞Fe＞Zn＞Cu。所得数据为松花粉的进一步研究和开发利用提供科学依据。Objective To measure mineral content of Pine Pollen and analyse the results. Methods Using micro- wave digestion atomic absorption method to pretreatment the sample, and 8 kind of mineral was tested by atomic ab- sorption for K, Ca, Na, Mg, Fe, Zn, Cu, Mn, and conduct the standard recovery and precision experiment. Results RSD of sample results was 0.018% - 1.781%, standard recovery of element was 90.0% - 101.1%. Conclusion The mineral content in Pine Pollen are Cu. All data provide scientific basis for rich, and the order of mineral content is K 〉 Mg 〉 Na 〉 Ca 〉 Mn 〉 Fe 〉 Zn 〉 Pine Pollen research.
