| 中文摘要: |
| 目的：测定一种原产地为加拿大的蜂胶中金属元素的含量，为进一步研究蜂胶营养价值提供数据，同时改进测量方法。方
法：用微波消解法处理样品,用硝酸和过氧化氢的混合物作为消解剂进行微波消解,并优化消解条件，然后用火焰原子吸收光谱法
测定蜂胶制品中钙、铁、镁、锌、钠、钾、铜的含量。结果：七种元素相对标准偏差为0.85 %~2.33 %(n=7),回收率在96.5 %~104.7 %之
间。试验结果表明该蜂胶中含有丰富的金属元素，且与河南产蜂胶相比，加拿大产蜂胶中多种金属元素含量远低于河南产蜂胶。
结论：使用本文方法测定蜂胶中的金属元素含量，结果准确，方法可靠。为进一步探讨蜂胶制品金属元素与其保健功能的关系提
供了有用数据。 |

| Objective: To determine the content of metal elements in a Canadian origin propolis and to provide data for further research
of propolis nutritional value, at the same time ,to improve the measurement methods. Methods: Propolis samples were treated by
microwave digestion using mixture of nitric acid and hydrogen peroxide as the digestion agent for digestion. The digestion conditions
were optimized. The content of calcium, iron, magnesium, zinc, sodium, potassium, copper in propolis products were determined by
flame atomic absorption spectrometry. Results: The value of relative standard deviation of 7 elements was 0.85 % ~ 2.33 % (n = 7). The
values of recovery were in the range of 96.5 % ~ 104.7 %. The results showed that the propolis is rich in metal elements. Compared with
the propolis produced in henan province,a variety of metals content of propolis from Canada is far lower than the propolis from henan.
Conclusion: This method of determination metals in propolis is reliable,and can get accurate results. The results provided useful data
for further research of the relationship of the metal elements and the health care function of propolis products |
