Abstract
Cultivated cannabis was divided into eight parts. The nondestructive neutron activation analysis using the monostandard method was applied to the each of leaves, male flower, and seed. Thirty-five kinds of elements were determined by this method from each sample. Following items on 29 kinds of elements, which were determined in most part of cannabis, were discussed : (1) Comparison of male and female cannabis, (2) comparison of the coefficient of variation among each part of cannabis, and (3) discussion on the elemental distribution pattern. On the basis of element concentration, the distribution pattern was divided into the following four classes : (1) Upper part<middle part<lower part. Al, Ba, Br, Ca, Cl, Cr, Fe, I, Sc, and rare earth elements belong to this pattern. (2) Upper part<middle part<lower part. Co, Cs, and Rb belong to this pattern. (3) Upper part=middle part=lower part. K, Mg, Mn, Na, and Zn belong to this pattern. (4) Others. Hg, In, and Sb belong to this pattern.
