摘要
借助电感耦合等离子体质谱法ICP-MS对3种地理标志苹果中的20种元素进行系统研究。结果发现:昌平苹果中Mo的含量最高,栖霞苹果次之,白水苹果最低;栖霞苹果中Rb的含量明显低于其余两种苹果,Mn、Co、Zn的含量明显高于其余两种苹果;昌平苹果中Cu的含量低于其余两种苹果,B、Ti的含量显著高于其余两种苹果;白水苹果中Ga和Ba的含量高于其余两种苹果。不同产地的地理标志苹果所含元素的种类和含量有较显著的差异。
To understand the differences in the contents of trace elements of apples from different geographical origins,20 trace elements in 9 Fuji apple samples from 3 growth regions were analyzed by inductively coupled plasma mass spectrometry（ICP-MS）.Results showed that Fuji apples from Changping,Qixia and Baishui regions ranked first,second and third in Mo content,respectively.Qixia apples exhibited a much lower Rb content but much higher Mn,Co and Zn contents than Changping and Baishui apples.The Cu content of Changping apples was lower than that of Qixia and Baishui apples,but much higher B and Ti contents were observed in Changping apples.Baishui apples contained higher Ga and Ba contents than Changping and Qixia apples.These data demonstrate the significant differences in the contents of trace elements of apples from different geographical origins.
