香菜微量元素的测定分析

目的:应用电感耦合等离子体发射光谱法(ICP-AES)测定了芫荽茎与叶中14种无机元素的含量。方法:用干法灰化样品,用外标法测定。结果:芫荽中钙、镁、铁、锌、锰、铜含量丰富,有害元素铅含量也比较高,茎与叶微量元素含量有差异。结论:芫荽含有较丰富的人体所需的微量元素,常少量食用,对身体健康有益。

Determination and Analysis of Trace Elements in Coriandrum sativum

Objective： The contents of 14 trace dements of stems and leaves in Coriandrum sativum have been detected respectively by ICP--AES. Methods： The sample was diluted by dry incineration, and the contents were determined by calibration curve method. Results： The results showed that Coriandrum sativum contained abundant trace dements of Ca, Mg, Fe, Zn, Mn, and Cu; the content of Pb which was harmful ingredient was high, too; there was difference of the contents of trace elements in stems and leaves. Conclusion： There are abundant trace elements which is necessary for people in Coriandrum sativum. It is healthy for people if we often eat like a bird.
