用荧光、极谱、原子吸收法检测出西洋参种子中的均含有16种无机元素，它们的含量各异，且因产地、参龄不同而异；其中11种人体必需宏、微量元素含量之和：集安三年＞国产均值＞原产美国＞左家四年＞集安四年，与所测元素加和量顺序完全一致；2种有害微量元素含量之和：集安三年＞原产美国＞集安四年＞国产均值＞左家四年，但都低于致毒量。
The 16 kinds of inorganic elements in the seeds of American ginseng were detected by fluorescence, polarographic and atomic absorption spectrometry. The contents of them were all different, and varied according to the origin and the age of the ginseng. Among them, 11 kinds of essential macronutrients and microelements : Ji’an three years> domestic average> Native America> left home four years> Ji’an four years, exactly the same with the order of the sum of the measured elements; sum of two harmful trace elements: Ji’an three years> origin United States> Ji’an four years> domestic average> left four years, but less than the toxic dose.
