Abstract: The chemical constituents in the fruit of Rosa davurica Pall. were studied. The silica gel column and thin layer chromatography methods were applied to isolate and purify the fruit of R.davurica cultivated in Jilin. The structure of the chemical constituents obtained were identified by modern spectrum analysis techniques and their physico-chemical properties. Seven compounds were isolated from the fruit of R.davurica. They were identified as α-D-(6-O-sinapoyl)-glucopyranosyl-β-D-(3-O-sinapoyl)-fructo-furanose(1), luteolin-7-O-rutinoside(2), hyperin(3), quercetin(4), isoliquiritigenin(5), β-daucosterol(6), β-sitosterol(7). Compounds 1, 2 and 5 were obtained in the fruit of R. davurica for the first time.

Key words: fruit of Rosa davurica Pall., isolate, purify, chemical constituent
