The methanolic extract of Rosa davurica Pall. roots exhibited strong antioxidant activity in a 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay and was found to be a dose-dependent inhibitor of non-enzymatic formation of advanced glycation end products (AGEs), which are relevant to diabetes complications. HPLC-diode array detector (DAD) analysis of the R. davurica Pall. root extract led to the identification of four compounds: hydrocaffeic acid, catechin, epicatechin, and ellagic acid. Catechin was present in the largest amount and exhibited high antiglycation activity. A CYP3A4 assay was used to investigate potential interactions between drugs and the extract, and results suggest that the R. davurica Pall. root extract had moderate potential for interfering with drug metabolism. The R. davurica Pall. extract did not display anti-inflammatory activity on the level of that for tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in a lipopolysaccharide (LPS)-stimulated macrophage assay; however, the extract did exhibit low to moderate immunostimulatory activity in a pro-inflammatory macrophage assay. Therefore, we conclude that R. davurica Pall. root is a promising anti-AGE agent with low to moderate risks of associated inflammation or drug interaction.
