Three sinapoyl glycosides have been isolated from the roots of Polygala virgata. The structures were established on the basis of UV, mass 1H and 13C NMR spectral data, including homonuclear and heteronuclear 2D shift correlation and selective INEPT experiments. alpha-D-(3-O-Sinapoyl)fructofuranosyl-alpha-D-(3-O-acetyl-6-O-s inapoyl)glucopyranoside and beta-D-(3,O-sinapoyl)fructofuranosyl-alpha-D-(4-O-acetyl-6-O-si napoyl)glucopyranoside are new natural products, whereas beta-D-(3-O-sinapoyl)fructofuranosyl-alpha-D-(6-O-sinapoyl) glucopyranoside has already been reported from other plants.
