[Objectives] To study the original plants, characters, tissue structure, powder characteristics and thin-layer chromatography (TLC) characteristics of Cardamine tangutorum and Cardamine macrophylla as Tibetan and Qiang edible and medicinal herbs, and to provide the basis for the identification of C. tangutorum and C. macrophylla. [Methods] The identification of C. macrophyU and C. tangutorum was carried out by original plant identification, character identification, microscopic identification and TLC identification. [Results] C. tangutorum and C. macrophylla can be distinguished according to the shape of rhizome and stem, the difference of stem leaves and leaflets, and the difference of flower color; there is no obvious difference between the characteristics of the shape and the powder; the thin layer chromatography shows that in the thin layer chromatography of C. tangutorum and C. macrophylla, spots with the same color are shown on the corresponding positions of the ground part and the reference substance quercetin; the underground part and the position corresponding to the reference substance ß-sitosterol all show the same color spots. [Conclusions] This study provides a reference for the identification of C. tangutorum and C. macrophylla.
