摘要
目的：以不同生长期多序岩黄芪根、茎、叶、花、果实样品为研究对象,研究生长期多序岩黄芪不同器官中无机元素的变化规律。方法：采用原子吸收分光光度法测定了不同时期多序岩黄芪各器官中13种无机元素含量,并分析各元素含量在不同时期多序岩黄芪器官中的相应变化特征。结果：多序岩黄芪根、茎、叶、花、果实中均含有丰富的无机元素,各器官中无机元素含量的特征变化与季节有关。多序岩黄芪药用部位根与非药用部位茎、叶、花、果实中Fe、Cu、Ca、Mn、Zn、Mg、Cr、Co、Na、Li、Ni、K含量随月份的改变呈现规律性变化,且在不同生长期存在极大值与极小值,Cd元素未检出;6～10月份Cu、Ca含量叶〉根〉茎,而叶中Mn元素含量均高于多序岩黄芪其他器官。结论：研究结果为多序岩黄芪采收时间的选择及非药用部位价值的开发提供参考依据。
Objective： To study the characteristics of inorganic elements in different organs of Hedysarum polybotrys in different growing variation,including root,rhizome,leaf,flower and fruit. Methods： The content of 13 inorganic elements in different organs were detected by using flame atomic absorption method,and then the characteristics of inorganic elements in different organs of Hedysarum polybotrys in different growing variation were analyzed. Results： There were abundant inorganic elements in root,rhizome,leaf,flower and fruit,the change in the contents of inorganic elements at different growing variation related to the season. The contents of Fe,Cu,Ca,Mn,Zn,Mg,Cr,Co,Na,Li,Ni and K were regularly changed with the change of growing variation,and Cd was not deteced. The content of Cu and Ca order was leaf〉 root〉rhizome,and the content of Mn at leaf was higher than that at other organs during June to October. Conclusion： The results provide scientific basis for the harvest time of Hedysari Radix and the development of non-medicinal portions.
