Abstract: Secondary metabolites of plants induced by environmental factors are highly variable, but the given metabolic pathways may have some phylogenetic implications. Due to the difficulty in complete and systematic collections in certain plant groups, the research on the correlation between secondary metabolites and phylogeny is limited. Based on the published papers, 377 secondary metabolites in the roots, stems, leaves and flowers of Syringa were collected, which mainly derived from the mevalonic acid pathway, deoxyxylulose-5-P pathway and shikimic acid pathway. After superimposing phylogenetic background, we found that dominance of a given type of secondary metabolites was high for the firstly diverged series, and the dominance declined for subsequently diverged series with the increase of chemical diversity. Phenylpropanoids and iridoids/secoiridoids were phylogenetically conserved. After superimposing geographical distributions, we found that some local species which were lately diverged had more diverse secondary metabolites compared with widespread species firstly diverged. The high proportion of lignans was highly related to the environmental pressure. This review provided a new clue for the systematic study on the variation pattern of chemical diversity in the taxa within genus in the light of evolution.
