温郁金根茎叶微量元素含量的测定

Determination of the Content of Trace Elements in Rhizome,Stalk and Leaf of Curcuma wenyujin

为分析比较温郁金不同部位微量元素的含量,用电感耦合等离子体原子发射光谱法(ICP-AES)测定了温郁金根、茎、叶中Ca、Cu、Fe、K、Mg、Mn、Ni、Zn等八种微量元素的含量,并对不同部位微量元素的含量进行了比较。结果表明,在其根茎叶中Ca、K、Mg、Mn含量较高,Zn、Ni、Mn含量有较大差异,Ca、K、Mg、Fe含量接近。从微量元素的角度来看,温郁金茎叶具有一定的应用价值。

The content of trace elements in the different parts such as rhizome, stalk and leaf in Curcuma wenyujin was determined by inductively coupled plasma spectrometry. Trace elements content in different parts was compared. The content of trace elements Ca, K, Mg, Mn were rich in rhizome, stalks and leaf, Ca, K, Mg, Fe content was similar in different parts, Zn, Ni, Mn content was much different. It is value to develop the stalk and leaf of Curcuma wenyujin.
