摘　　要：应用电感耦合等离子体质谱(ICP-MS)测定了收集于9个采样点的油菜蜜及其蜜源油菜花和油菜杆中Na,Mg,P,K,Ca,Mn,Zn,Rb,Sr和Ba等10种元素。在油菜蜜、油菜花和油菜杆中K,P,Ca,Mg和Na等五种元素含量均明显高于Zn,Rb,Mn,Sr和Ba,前五种元素含量大小顺序为K>P>Ca>Mg>Na,后五种元素含量在三者中的大小顺序则不尽相同。油菜花和油菜杆中K,P和Ca三种元素的含量均高于1 000mg·kg-1,油菜花中P,Ca,Mn,Zn和Rb等五种元素的平均含量均高于油菜杆,可以初步推断油菜花富集元素的能力略强于油菜杆。在上述测定结果基础上,首次应用雷达图对油菜蜜及其蜜源油菜花和油菜杆中10种元素的关系进行了研究,主要是为了对将油菜花中元素含量用于蜂蜜溯源研究的可能性进行探索。从雷达图可以看出,10种元素在油菜蜜、油菜花和油菜杆中的星形基本类似。此研究为油菜蜜的相关研究提供基础数据,同时为利用油菜花中元素含量代替油菜蜜中元素含量进行油菜蜜溯源提供了一定的科学依据。The determination of 10 trace elements including Na ,Mg ,P ,K ,Ca ,Mn ,Zn ,Rb ,Sr and Ba ,in rape honey and its corresponding rape flower and stem gathered from nine sampling sites was carried out by in-ductively coupled plasma mass spectrometry （ICP-MS） .The contents of K ,P ,Ca ,Mg and Na were obviously higher than Zn ,Rb ,Mn ,Sr and Ba in rape honey ,rape flower and rape stem .For the first five elements ,K had the highest content ,followed by P ,Ca ,Mg and Na .However ,the order of content for latter five ele-ments was not the same in different matrixes .The contents of K ,P and Ca were all higher than 1 000 mg ＆#183; kg -1 in rape flower and rape stem ,while the contents of P ,Ca ,Mn ,Zn and Rb in rape flower were slightly higher than in rape stem .It can be concluded that rape flower showed slightly higher concentrating ability for trace elements than rape stem .Based on these results ,radar chart was firstly applied to research the relation-ship of 10 elements in rape honey and its corresponding rape flower and stem .The aim of the present work was to study the possibility of using trace elements contents in rape flower to trace the geographical and botanical origin of honey instead of rape honey .It can be found from the radar charts that the stars of rape honey ,rape flower and rape stem were similar to each other .This research not only provides the basic data of trace ele-ments in comparative study of rape honey ,but also gives scientific basis for tracing the origin of rape honey ac-cording to the trace elements in corresponding rape flower that replaces those of rape honey .
