Online two-dimensional liquid chromatography was used for the comparative composition analysis of the pericarp of Euscaphis japonica var. wupingensis and E. japonica. The results showed that the two-dimensional RPLC×RPLC chromatograms were similar intraspecies, but some components were still different. In addition, heart-cutting two-dimensional chromatography was used to localize the three differential components between these two species. This experiment provided reference for the chemical differentiation of E. japonica var. wupingensis and E. japonica.
