Chenotaxonomical research on the genus Aconitum (Ranunclaceae) of Northeastern Asia was discussed on the biotransformation of diterpene alkaloids of several species. For examples: A. macroyesoense derived from A. yesoense has an ability of biotransformation of lycoctonine-type alkaloids e.g. delcosine and browniine against aconine-type alkaloids e.g. neoline and chasmanine in A. yesoense. This moment in time is an era of natural mutation of A. yesoense. The phenotypic plasticity is exactly defined as chemical selection of the secondary metabolite and physical selection of morphological or geometrical term. The chloroplast DNA analysis shows the pedegree of the species. However, The above analysis for the tetraploids complex in Japanese Aconitum showed results of disorder. From the absolute structure for the characteristic diterpene alkaloids in some certain species, the life history of the vegetation was clarified from phenomenon in the transplant of Japanese Aconitum teraploids.(e.g.A. grossedentatum-(A. montanum)-A. subcuneatum.) On the basis of chemical research on the surrounding nitrogen atom, it is suggested that subgenus Gymnaconitum is near to an origin of the primitive angiosperms.
