Abstract: AIM：To investigate the chemical constituents of Geranium dahuricum DC. METHODS: Components were separated by means of solvent extraction and chromatography on Toyopeal and Sephadex-LH20, The structures were determined by spectral analysis and chemical evidences. RESULTS: Five compounds were obtained and elucidated as methyl 3-O-(β-D-glucopyranosyl) gallate (I), methyl 3-O-［β-D-(6′-O-galloyl)-glucopyranosyl］ gallate (II), quercetin-3-O-β-D-galactopyranoside (III), myricetin-3-O-β-D-galactopyranoside (IV), myricetin-3-O-α-L-rhamnopyranoside (V). CONCLUSION: These compounds were separated from this plant for the first time, where I and II were new natural products.
