Analysis and identification of eight kinds of metallic elements in Corylus Heterophylla flowers

目的:分析鉴别榛花中八种金属元素。方法:榛花样品经干法或湿法处理后,以火焰原子吸收光谱法测定榛花中Na、Mg、Ca、Mn、Fe、Cu、Zn、Pb等八种金属元素的含量。结果:榛花中Na、Mg、Ca、Mn、Fe、Cu、Zn、Pb元素的平均含量分别为0.0833mg/g、0.3576mg/g、1.7518mg/g、0.4858mg/g、0.1217mg/g、0.0812mg/g、0.2810mg/g、0.0557mg/g,其中Ca含量较高。结论:该测定方法简单、快速,结果准确,为榛花进一步开发利用提供了科学依据。

Objective： To analyze and identify eight kinds of metallic elements in Corylus Heterophylla flowers. Methods： After having been digested in dry process or wet process separately, the metallic elements of Corylus Heterophylla flowers were determined by flame atomic absorption spectrometry. Results： In samples, average concentrations of Na, Mg, Ca, Mn, Fe, Cu, Zn and Pb were 0. 0833mg/g, 0. 3576mg/g, 1. 7518mg/g, 0. 4858mg/g, 0. 1217mg/g, 0. 0812mg/g, 0. 2810mg/g, 0. 0557mg/g, respectively. Among the 8 kinds of metallic elements, Calcium is the richest in Corylus Heterophylla flowers. Conclusion： This method is simple, rapid and accurate, which also provides a scientific basis for the further development and utilization of Corylus Heterophylla flowers.
