title: The 14-MeV neutron activation analysis of Chinese medicines for protein, phosphorus, potassium and magnesium contents (II).
abstract: Elementary form of nitrogen (protein), phosphorus, potassium and magnesium contained in 180 different kinds of Chinese medicines are analyzed by means of 14-MeV neutron activation technique. The percent contents of these elements in the Chinese medicines range from 0 to 34.41% (average: 11.73%) for protein, from 0.03 to 37.42% (average: 1.72%) for phosphorus, from 0.12 to 33.22% (average: 2.94%) for potassium and 0.03 to 5.62% (average: 0.43%) for magnesium. Comparison of the present results with the previous measurements for another 66 kinds of Chinese medicines is made.
