Some metallic ions such as copper, manganese, iron, zinc and cadmium in ginseng extract, originated from white ginseng, were determined by atomic absorption spectrophotometry. The extracts were prepared with water, 35% ethanol, 50% ethanol or 75% ethanol solution followed by filtration or centrifugation. Greater amounts of metallic ions were found in the solution filtrated by filter paper (Toyo No. 5A) or by filter cloth than in that of centrifugation. The residual amount of metallic ions in the extract decreased with increasing concentration of ethanol. The percentages of each metallic ion in ginseng extracts on the basis of original amount of metallic ions were as follows: Cu, 10.4-31.9%, Fe,5.1-19.0%, Mn,3.0-12.2% Zn,7.4-12.0%, Cd,5.9-11.8%.
