New Galloylated Flavonoid Glycosides from Geranium stepporum DAVIS

Summary, in English

Two new galloylated flavonoid glycosides, quercetin-3-O-(3 ''-O-galloyl)-beta-glucopyranoside (1) and quercetin-3-O-(3 ''-O-galloyl)-beta-galactopyranoside (2) were isolated from the aerial parts of Geranium stepporum along with the four known flavonoids, quercetin 3-O-beta-glucopyranoside (3), quercetin 3-O-beta-galactopyranoside (4), quercetin 3-O-(6 ''-O-galloyl)-beta-glucopyrinoside (5) and quercetin 3-O-(6 ''-O-galloyl)-beta-galactopyranoside (6). The structure elucidation of the isolated compounds was accomplished by spectroscopic methods (UV, 1D- and 2D-NMR, and ESI-TOF-MS).
