Four glycosides, rosamultin (1), tetracentronside B (2), 4-O-methylellagic acid 3-O-${alpha}$-$_L$-rhamnopyranoside (3), and vanillic acid 4-O-${eta}$-$_L$-glucopyranoside (4), isolated from the roots extract of Potentilla discolor, were subjected to in vitro bioassays to evaluate the inhibitory activity on advanced glycation end products (AGEs) formation and rat lens aldose reductase (RLAR). Compound 3 exhibited a significant inhibitory activity against both AGEs formation and RLAR with IC$_{50}$ values of 79.5 and 8.03 ${mu}$M, respectively. All the compounds (1-4) were isolated for the first time from this plant.
