摘要：目的探讨当归药材中无机元素的质量分数与其生长的海拔及经纬度的关系。方法采用AAS(原子吸收分光光度法)测定甘肃省10个主产区的91批不同海拔及经纬度的当归药材中9种无机元素(Fe、K、Zn、Mg、Mn、Ca、Ni、Na和Cu),采用相关分析、通径分析和决定程度分析进行研究。结果不同产地当归中无机元素的质量分数大多有显著性差异;当归药材中Na的质量分数与海拔呈显著正相关,K、Cu的质量分数与经度及纬度呈显著正相关,Ca的质量分数与海拔呈显著负相关;海拔和经纬度对Mg、Zn及Ni的质量分数存在一定的交互作用;海拔是K和Mn的主要影响因素,经度是Ca、Ni和Na的主要影响因素,纬度是Ca和Mg的主要影响因素。结论在当归种植基地选择时须考虑海拔、经度及纬度等地理指标以富集人体必需的微量元素,减少重金属元素。
AIM To investigate the relationship between inorganic elements content of Angelica sinensis and its growing altitude,latitude and longitude.METHODS The contents of nine kinds of inorganic elements（ Zn,Fe,Mn,Mg,Ni,Ca,Na,K and Cu） in 91 batches of A.sinensis from ten growing areas with different growing altitude,latitude and longitude were determined by AAS（ atomic absorption spectroscopy）.Correlation analysis,path analysis and decision coefficient analysis were used for study.RESULTS The content of inorganic elements in A.sinensis had significant differences among the most growing areas.Na level with altitude,K and Cu levels with latitude and longitude had a significant positive correlation,Ca level had a significant negative correlation with altitude.Their interaction manifested that altitude affected K and Mn levels,latitude represented the decision factor of Ca,Ni and Na levels,and longitude was the main influencing factor of Ca and Mg,respectively.CONCLUSION The growing altitude,latitude and longitude must be considered in order to concentrate beneficial trace elements and reduce harmful trace elements to human being in the selection of growing areas of A.sinensis.
