Elementary form of nitrogen (protein), phosphorus, potassium and magnesium contained in sixty-six different kinds of Chinese medicines were analyzed by means of 14-MeV neutron activation technique. The % contents of these elements in Chinese medicines range from 4.1 to 38.6% (average: 12.7%) for protein, 0.1 to 10.5% (average: 1.3%) for phosphorus, 1.6 to 13.8% (average 4.5%) for potassium and 0.1 to 2.5% (average: 0.5%) for magnesium. The procedure proves to be quite precise and potentially quite accurate, while only requiring about 20 minutes per sample. The methods of determining the elements are described.
采用14兆电子伏中子活化技术分析了66种不同中药中氮（蛋白质）、磷、钾和镁的基本形态。这些元素在中药中的含量百分比为：蛋白质4.1%至38.6%（平均12.7%），磷0.1%至10.5%（平均1.3%），钾1.6%至13.8%（平均4.5%），镁0.1%至2.5%（平均0.5%）。该方法证明相当精确且可能非常准确，同时每个样品仅需约20分钟。文中描述了测定这些元素的方法。
