Abstract: Based on the research results of structures, this paper discusses the biomimetic synthesis and chemical relationship of diterpenoids and diterpene alkaloids, as well as comprehensive in-formation including geographic distribution, cytology and morphology of Spiraea japonica com-plex, chemotaxonomy of this complex. (1) Diterpenoid bearing aldehyde group is a possible biosynthetic predecessor of spiramine alkaloids. (2) Spiraea japonica complex is a particular and relatively independent group in Spiraea. (3) South and West China especially Hengduan Mountain is the centre of modern differentiation, probably the original centre of this complex. (4) Some vari-eties have been combined.

Key words: Spiraea Pponica
