中文摘要:目的：为了弄清黄花菜不同部位对钾、钙、镁、铁、锰、锌、铜、镍、硒、铬、镉、砷和铅13个矿质元素的积累趋势，为黄花菜植物资源提供基础数据，并提出优化资源利用的设想。方法：利用电感耦合等离子体质谱仪（inductively coupled plasm-mass spectrometry，ICP-MS）对黄花菜不同产地、不同品种和不同部位的样品，以及黄花菜产地土壤样品中的13个矿质元素进行检测。结果：除去污染元素，黄花菜各器官中均以钾、镁、钙元素的含量最高，铁、锰、锌元素的含量次之，铜、镍以及硒元素的含量最低；黄花菜的花蕾与叶片是多种必需矿质元素主要积累的部位，锌元素在花蕾部位含量最高，钾、镁、钙、锰元素在叶片部位含量最高，铁、铜元素在根部含量最高；黄花菜的花蕾基本不积累污染元素。结论：不同产地的黄花菜花蕾都达到了食用安全标准，同时根、花葶和叶部位也富含对人体有益的各种微量元素，为更科学合理地加以开发利用黄花菜资源提供基础研究数据。

Study on Distribution and Accumulation of Different Mineral Elements in Hemerocallis citrina Baroni Based on ICP-MS Analysis

Abstract:Objective：In order to clarify the accumulation trend of 13 kinds of mineral elements such as K，Ca，Mg，Fe，Mn，Zn，Cu，Ni，Se，Cr，Cd，As and Pb，provide basic data for Hemerocallis citrina Baroni resources，and put forward the idea of optimizing the use of resources.Methods：The 13 kinds of mineral elements in samples from different habitats，different varieties，different parts of H.citrina plants and H.citrina producing areas were detected by inductively coupled plasma-mass spectrometry （ICP-MS）.Results：Exclusive of contaminated elements，the contents of K，Mn and Ca were the highest in the organs of H.citrina，and the contents of Cu，Ni and Se were the lowest.The flower buds and leaves of H.citrina were the main parts that accumulate a variety of essential mineral elements.The contents of Zn in the flower buds was the highest，the contents of K，Mg，Ca and Mn in the leaves were the highest，and the contents of Fe and Cu were the highest in the root.The flower buds of the H.citrina was basically not rich in heavy metal elements.Conclusion：Different origins of the H.citrina flower buds have reached the food safety standards，and the other parts of H.citrina also rich in a variety of trace elements that beneficial to the human body.The results provide basic data for more scientific and rational development and use of H.citrina.
