摘要：目的:测定甘肃不同产地红芪中微量元素含量,为有效控制其质量提供基础性数据。方法:利用湿消化法处理样品,采用火焰原子吸收光谱法测定不同产地红芪样品中铁,铜,钙,锰,锌,镁,镉,铬,钴,钠,锂,镍,钾元素含量,并进行方差分析和聚类分析。结果:红芪中钙、钾、锌、锰、钴、锂、铬、镁、铜、铁、钠、镍的含量范围为2.770 1~3.411 6,16.695 9~18.753 5,2.732 2~6.482 0,0.797 6~0.994 4,0.067 0~0.071 6,0.341 2~0.423 0,0.059 9~0.068 9,88.725 8~99.263 5,0.185 6~0.467 3,0.865 9~2.607 1,20.758 5~27.021 8,0.196 6~0.232 4μg·g^(^(-1))。其中镉元素未检出,红芪中各元素平均含量高低顺序为镁>钠>钾>锌>钙>铁>锰>锂>铜>镍>钴>铬>镉;32个产地红芪中铁、钾、锌、镍、钠、镁、锰、铬元素含量之间均具有显著性(P<0.05)差异,而铜、钙、锂、钴4种元素的含量之间没有显著性差异;32份样品聚为4类,大多数栽培红芪聚第一类,野生红芪聚为第二类。结论:红芪中微量元素含量的差异性不仅与产地有关,而且与红芪是野生品、栽培品有关。
Objective： To determine the contents of trace elements in Hedysari Radix from different places in Gansu province,and provide reliable method for the effective quality control of Hedysari Radix. Method：Wet digestion method was used to process the samples and flame atomic absorption spectrometry was used to determine the contents of Fe,Cu,Ca,Mn,Zn,Mg,Cd,Cr,Co,Na,Li,Ni and K in Hedysari Radix. The analysis of variance and clustering analysis were applied to analyze the results. Result： The elemental contents in Hedysari Radix were as follows： Fe（ 0. 865 9-2. 607 1 μg·g-1）,Cu（ 0. 185 6-0. 467 3 μg·g-1）,Ca（ 2. 770 1-3. 411 6 μg·g-1）,Mn（ 0. 797 6-0. 994 4 μg·g-1）,Zn（ 2. 732 2-6. 482 0 μg·g-1）,Mg（ 88. 725 8-99. 263 5μg·g-1）,Ni（ 0. 196 6-0. 232 4 μg·g-1）,Cr（ 0. 059 9-0. 068 9 μg·g-1）,Co（ 0. 067 0-0. 071 6 μg·g-1）,Na（ 20. 758 5-27. 021 8 μg·g-1）,Li（ 0. 341 2-0. 423 0 μg·g-1）,K（ 16. 695 9-18. 753 5 μg·g-1）. Cd was not detected in Hedysari Radix. The order for average elemental contents was Mg〉 Na〉 K〉 Zn 〉 Ca 〉 Fe〉 Mn〉 Li〉 Cu〉 Ni〉 Co〉 Cr 〉 Cd from high to low. There was significant difference in contents of Fe,K,Zn,Ni,Na,Mg,Mn and Cr（ P〈0. 05）,but the difference was not significant in contents of Cu,Ca,Li and Co in Hedysari Radix from 32 places. The results of clustering analysis showed that 32 samples were clustered into four different groups.The majority of cultivated Hedysari Radix samples were classified into the first group,and wild Hedysari Radix samples were classified into the second group. Conclusion： The differences of trace elements content in Hedysari Radix are not only related to places,but also related to cultivated Hedysari Radix or wild Hedysari Radix.
