五味子及其发酵品中微量元素含量的测定

Determination of Trace Elements in Schisandra and Fermentation Products

采用空气-乙炔原子吸收法测定五味子、五味子酒以及五味子发酵果渣中微量元素的含量。用微波消解法对样品进行前处理,各元素标准溶液逐级稀释,测定标准系列的吸光度值,绘制标准曲线。结果表明:对于所测元素,标准曲线回归方程相关系数R2>0.997 3;测得五味子及其发酵品中钾、钙、钠、镁、铁、锌、锰、铜8种微量元素,其中钾、镁、钙、钠、锰元素含量较高,铁、铜、锌元素含量相对较低。所得数据为五味子药材及其发酵品的进一步研究及开发提供了数据参考及支持。

To determine the content of trace element in schisandra, Schisandra wine and fructus schisandrae pomace fermentation by Aircetylene atomic absorption spectrometry.Sample was pre-treated using microwave digestion method. All element standard solution was diluted stepwise. Absorbance value of standard series was tested and standard curve was drawn. The results of standard curve correlation coefficient was R^2〉0.997 3. Potassium, calcium, sodium, magnesium, iron, zinc, manganese, copper were tested in schisandra and potassium.which Potassium, magnesium, calcium, sodium, manganese content was higher, Iron, copper and zinc content is relatively low. The results provided the referance and support for the further research and development of schisandrae chinensis and potassium.
