Abstract: In order to quickly identify the adaptability of color-leaf plants on saline-alkali soil, eight kinds of colorful leaf plants were used as materials to study the effects of different saline-alkali soils on the main components of color-leaf leaves. The results showed that the main components of the leaves of Coleus blumei were sugar, protein and lipid. With the increase of soil salinity, the content of carbohydrates corresponding to functional group C――H and sugar ring increased by Sophora japonica and Ligustrum vicaryi, and decreased by Ulmus pumila cv ‘Jinye’, Prunus×cistena N, Amygdalus persica f, and Berberis thunbergii var; The increase of the carbohydrates corresponding to functional group C――O and C――C is in the Ligustrum vicaryi, and the drop is in Ehrh.f.atropurpurea jacq, Prunus×cistena N, and Berberis thunbergii var. The content of the protein(amide Ⅲ band)corresponding to the functional group C――O in the Prunus×cistena N. decreased; the protein corresponding to the functional group C==O of the Sophora japonica, Ligustrum vicaryi, Prunus×cistena N, Amygdalus persica f, Berberis thunbergii var. and Ehrh.f.atropurpurea jacq increased firstly and then decreased. The content of lipids in the functional group C――H of the Ulmus pumila cv Jinye, Prunus×cistena N and Amygdalus persica f. decreased, and the content of Berberis thunbergii var. increased.
