Abstract:To determine the content of trace element in schisandra， Schisandra wine and fructus schisandrae pomace fermentation by Air-acetylene 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 R2>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 devel－ opment of schisandrae chinensis and potassium.
