摘要
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.
