In order to explore the differences in the metabolites and metabolic pathways of leaves from wild Rosa acicularis and R. acicularis‘Luhe’，a GC-MS non-targeted metabolomics test was carried out on the leaves of two kinds of R. acicularis，6 amino acids，12 sugars，four alkanes，17 organic acids，five esters and seven other compounds and a total of 51 metabolites were detected respectively. The PCA model was in line with expectations and the OPLS-DA model screened out 19 significantly different metabolites. The analysis of differential metabolic pathways revealed a total of five major differential metabolic pathways. Based on the results， there were significant differences in the metabolism of some organic acids and sugars in as well as in the ABC transporter， phenylpropane biosynthesis， benzoic acid degradation and the metabolism of alanine， aspartic acid and glutamic acid in the leaves of the two species of R. acicularis. It was speculated that there were significant differences in leaf photosynthetic efficiency and resistance to stress， but further study was needed in combination with genome， proteome， transcriptome and other methods.
